The number of moles of the gas is 0.0396 moles.

<h3>What is the ideal gas equation?</h3>

The ideal gas equation is used to determine the relationship between the variables; temperature, pressure, volume and the number of moles of a gas. We know that the gas laws are used to understudy the parameters that has to do with gases.

Thus;

Volume = 1000.0 cm 3 or 1 L

Gas constant = 0.082 atmLK-1Mol-1

Temperature = 32 o C + 273 K = 305 K

Pressure = 752 mm Hg or 0.99 atm

Thus;

PV = nRT

n = PV/RT

n = 0.99 atm * 1 L/0.082 atmLK-1Mol-1 * 305 K

n = 0.0396 moles
