If you have a certain volume of a liquid in a beaker and you want its mass/weight, you must first find the weight of the empty beaker. You could weigh the liquid, pour it out of the beaker, and then weigh the beaker and subtract its weight from the weight of the beaker-plus-liquid.

Procedure

1. Find the mass of an empty graduated cylinder.
2. Pour 100 mL of water into the graduated cylinder.
3. Weigh the graduated cylinder with the water in it.
4. Find the mass of only the water by subtracting the mass of the empty graduated cylinder.
5. Use the mass and volume of the water to calculate density.

The mass of an object can be calculated in a number of different ways:

1. mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume.
2. mass=force÷acceleration (m=F/a).
3. mass=weight÷gravitational acceleration (m=W/g).

Divide the object’s weight by the acceleration of gravity to find the mass. You’ll need to convert the weight units to Newtons. For example, 1 kg = 9.807 N. If you’re measuring the mass of an object on Earth, divide the weight in Newtons by the acceleration of gravity on Earth (9.8 meters/second2) to get mass.

We know that mass equals net force divided by acceleration.

Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).

Since density is equal to mass divided by volume, then volume must be equal to mass divided by density. Therefore, to calculate volume, simply divide the number derived in Step 1 by the number obtained in Step 2.

How can I find mass with density and volume?

1. Look up the density of the material the object is made of in kg/m³.
2. Measure the volume of the object in m³.
3. Multiply the density by the volume.
4. You will then have the mass of the object in kg.

To find an object’s mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G).

Originally Answered: How do we find the volume of an object without knowing neither the density nor the mass? The formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The formula can use any two of the values to calculate the third. Density is defined as mass per unit volume.

Tools Used to Measure Mass

• Balances and Scales. For most everyday objects, scientists use a balance to obtain an object’s mass.
• Space Linear Acceleration Mass Measurement Device (SLAMMD)
• Measurement Transducer.
• Vibrating Tube Mass Sensor.
• Gravitational Interaction.

Based on the latest breakthroughs in particle physics, the answer is a plain NO – it’s not possible for a massive particle to have no volume. In fact, it is NOT possible for any particle, whether massive or massless, to have zero volume. Particles that do not interact are massless, those that do exhibits mass.

1. The density of an object determines whether it will float or sink in another substance.
2. An object will float if it is less dense than the liquid it is placed in.
3. An object will sink if it is more dense than the liquid it is placed in.

Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.

If an object is more compact, or denser, than water, it will sink in water. If the density of an object is less than the density of water, the object will float in water. A ship floats when it can displace water equal to its own weight.

Since the pebble displaces the volume of water equal to its volume, the change in the water level is the volume of the pebble. By subtracting the initial water level from the final water level, we can find the volume of the pebble: 280 mL – 200 mL = 80 mL….

Gravity isn’t affected at all by being underwater. Gravity is a pull between any two objects. But it’s very weak so it isn’t detectable unless one of the objects is huge — like the earth. The force of gravity is called the weight and depends on two things: the puller and the pullee.

There are three types of Buoyancy which are positive, negative and neutral.

Humans are naturally positively buoyant, as is most of the scuba equipment we use. Because of this, we need to use weights to help us descend, and stay comfortably underwater.

Swimming relies on the nearly neutral buoyancy of the human body. On average, the body has a relative density of 0.98 compared to water, which causes the body to float. However, buoyancy varies on the basis of body composition, lung inflation, muscle and fat content, centre of gravity and the salinity of the water.

What Is The Freefall? We are positively buoyant at the surface, and add weights to make ourselves neutrally buoyant at around 10-15m (32-49ft) since most shallow water blackouts occur between 10m (32ft) and the surface; this is a safety concept.

There’s the basic ballpark method — carry 10 percent of your body weight in lead. Or there’s the surface float method — in full scuba gear, load enough weight to enable you to float with the water at eye level (some would say at the hairline).

If an object has a greater density than water, it sinks. If it is less dense than water, it floats. Salt dissolved in the water makes it more dense. So even if you haven’t changed your body composition, you are less dense relative to the salty water, which helps you float on the surface.
