Determine the number of moles of air present in 1.35 l at 750 torr and 17.0°c. ideal gas law formula: pv = nrt(r = 62.396 l•torr
Tatiana [17]

The number of moles of air present is 0.056 mole

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

The ideal gas is one in which molecules do not attract or repel each other.Many gases like oxygen,nitrogen, carbon di oxide can be treated as the ideal gases as particular temperature and pressure.The real gases at high temperature and lower pressure can be treated as ideal gases.

The given data in the question is

Volume = 1.35 L

Pressure (P) = 750 torr

Temperature (T) = 17 °C = 17 + 273 = 290 K

Gas constant (R) = 62.396 L•torr/mol•K

The number of moles (n) =?

How to determine the number of moles:

The number of moles present can be obtained by using the ideal gas equation as illustrated below:

PV=nRT

Divide both sides by RT

n=\dfrac{PV}{RT}

n=\dfrac{(750\times 1.350}{62.396\times 290)}

n=0.056\ moles

Hence, the number of moles of air present is 0.056 mole

To learn more about the ideal gas equation follow
