Asample of nitrogen gas, n2, is collected in a100 ml container at a pressure of 688 mm hg and a temperature of 565 °c. how many grams of nitrogen gas are present in this sample?

The mass of nitrogen gas present in the given sample is 0.037 g

Explanation:

To calculate the number of moles, we use the equation given by ideal gas equation:

Or,

where,

P = Pressure of the gas = 688 mmHg

V = Volume of gas = 100 mL = 0.1 L    (Conversion factor:  1 L = 1000 mL)

m = Mass of nitrogen gas = ?

M = Molar mass of nitrogen gas = 28 g/mol

R = Gas constant =

T = Temperature of the gas =

Putting values in above equation, we get:

Hence, the mass of nitrogen gas present in the given sample is 0.037 g
