Question

3. A sample of a gas has a mass of 1.25 g and a volume of 1000 cubic centimeters. Solve for density and

identify the gas.

Answer 1

The density of the gas is 0.00125 g/cc and the gas is Air.

Step-by-step explanation:

Given,

mass of gas = 1.25 grams

Volume = 1000 cc.

Density = ?

Density of the gas can be found by using the formula

Density = Mass/Volume

Substituting the values we get,

Density = 1.25/1000 = 0.00125 g/cc.

The gas is air because at room temperature and pressure air has a density of 0.00125 g/cc.
