Question

24. A 12.39 10m vessel at 298K contains 1 mole of CO2, 3 moles N2, 20g H2 and 12g He at a
total pressure of 34 bar. The partial pressure of H2 in the mixture is​

Answer 1

ANSWER

2 g of hydrogen, 8g of oxygen and 22 g of carbon dioxide corresponds to

$\frac{2}{2} = 1$

mole of hydrogen,

$\frac{32}{8} = 0.25$

moles of oxygen and

$\frac{22}{44} = 0.5$

moles of carbon dioxide.

The total number of moles are =1+0.25+0.5=1.75 moles.

The temperature is 0+273=273K

The total pressure is

$p \: = \frac{nrt}{v}$

$p \: = \frac{1.75 \times 0.0821 \times 273}{22.4} = 1.75atm$
