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.

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

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.

the answer

explanation:

the capillary tube was too close to the bottom of the beaker.

the ruler may have moved.

water got into the capillary tube.

the temperature was not allowed to equilibrate in the 2-4 minutes.
