A volume of 18.0 L contains a mixture of 0.250 mole N2 , 0.250 mole O2 , and an unknown quantity of He . The temperature of the

tatiyna

There are 1.22 grams of He in the mixture. The mixture contains 0.304 moles of He, 0.250 moles of N2 and 0.250 moles of O2. Since the mixture of gases are at standard temperature and pressure, the total moles of the mixture equivalent to 18.0 L is 0.804 moles.

Further Explanation:

At standard temperature and pressure of 0°C and 1.00 atm, the molar volume of gas is 22.4 L.

From this, the total moles of the mixture can be derived using the solution below:

$total \ mol \ of \ gases \ = 18.0 \ L (\frac{1 \ mol \ }{22.4 \ L})\\$
