Question

A 5litre flask contains 3.5g of nitrogen, 3g of hydrogen, 8g of oxygen at 27°c find the total pressure exerted by the mixture of these gases

Answer 1

Answer:

Partial pressure of N₂=[27⁰+273=300k]

P(component)=n(component)×R×T ÷ V

Pn₂=3.5/28×0.0821×300 ÷ 5

    = 0.615atm

PH₂=3/2×0.0821×300 ÷ 5

      = 7.389atm

P0₂=8/32×0.0821×300 ÷ 5

     =1.231atm

=total pressure :

 =0.615+7.389+1.231

= 9.71atm
