Question

89. A container contains H2 and CO in the mass ratio of
1:2. The molar ratio of the two gases in the mixture
is
(1) 1:2
(3) 5:1
(2) 3:2
(4) 7:1​

Answer 1

Explanation:

this is the answer.hope it helps

Answer 2

The molar ratio of the two gases in the mixture  is 7:1

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.  

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}$

a) $\text{Moles of hydrogen}=\frac{1g}{2g/mol}mol$

b) $\text{Moles of carbon monoxide}=\frac{2g}{28g/mol}mol$

The molar ratio of of the two gases in the mixture is $\frac{\frac{1}{2}}{\frac{2}{28}}=7:1$
