Question

A mixture of N2 and Co, at one atm pressure
contains 56% by weight of N2. Partial pressure of
N, in the mixture will be [NCERT Pg. 146]
(1) 0.56 atm
(2) 0.44 atm
(3) 0.67 atm
(4) 0.33 atm​

Answer 1

Answer:

the correct answer is 0.67 please mark me brainless please

Answer 2

Answer:

0.667atm

Explanation:

Given, N2 =56% therefore CO2 = 44%

Let us consider the mixture to be 100g

Therefore, moles of N2 = 56/28=2 moles

moles of CO2 = 44/44= 1 mole

Partial Pressure of gas= Mole fraction of the gas *Total pressure

Tp = 1atm(given)

Therefore, partial pressure of N2= 2/3*1 = 0.667atm
