The mass of pure CH, gas to be mixed with 70g of pure CO so that partial pressure of CO isequal to the partial pressure of CH, isIS -

Answer»

For partial pressure to be same.. , no. of moles of both the gasses should be same.

moles of CO = 70/28 = 5/2 moles = 2.5 moles

now moles of CH4 should be 2.5 so, mass = 2.5*16 = 40g
