Answer:
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.
