Q. How do you find the mass of water with density?
Example Problem
- mass = volume x density.
- mass = 30 ml x 0.790 g/ml.
- mass = 23.7 g.
Q. Which is denser an object that has a density of 1000 kg m3 or one that has a density of 1g cm3?
Which is denser: an object that has a density of 1000 kg/m3 or one that has a density of 1 g/cm3? They are the same density. Iridium is not the heaviest atom found in nature. The iridium atoms are closer together in the crystalline form.

Q. What is density of oxygen?
| Molecular Weight: | 32.00 |
|---|---|
| Triple Point Pressure: | 0.0015 atm |
| Density, Gas @ 0° C, 1 atm: | 1.4291 g/l |
| Density, Liquid @ b.p.: | 1.141 g/ml |
| Density, Liquid @ t.p: | 1.31 g/ml |
Q. What is the volume in Litres of 0.1 m h2so4?
V1=2. 5 litre.
Q. What volume of oxygen affects complete combustion?
According to reaction, At STP; 1 mole of acetylene that is 22.4L require moles of oxygen that is ×22.4=56L for complete combustion.
Q. What volume of oxygen at NTP is needed?
Answer: 1 mole of acetylene requires 2.5 moles of oxygen for complete combustion. At NTP, 22.4 liters of acetylene requires = 2.5 x 22.4 L of oxygen.
Q. What volume of oxygen at STP is needed to cause complete combustion of 200 mL of methane?
∴ 200 mL of C2H2 at N.T.P form CO2=2×200 mL = 400 mL.
Q. What volume of oxygen at STP is required to affect the combustion of 200?
What volume of oxygen at STP is required to affect complete combustion of 200 cm3 of acetylene and what would be the volume of carbondioxide formed? Thus volume of O2 required = 500 cm3 at S.T.P. According to Gay Lussac’s law of gaseous volumes.
Q. What volume of oxygen is required for the complete combustion of 2 volumes of acetylene gas at NTP?
From the reaction combustion of 2 volumes of acetylene gas at NTP requires 5 volumes of dioxygen.
Q. What is the volume of 2 mol of chlorine gas at STP?
At STP, the molar volume of all gases is 22.4dm3/mol . Hence 2mol of Cl2 at STP occupies a volume of 44.8dm3 .
Q. What is the volume of 2 moles of nitrogen gas at STP?
Explanation: One mole of gas has a volume of 22.4L at STP. Since there are two moles of gas present, the volume is doubled.
Q. What is the volume of 1 mole of chlorine gas at STP?
22.7 L
