Question

IF THE Ratio of masses of N2 and O2 gases confined in a vessel is 2:1 .then the ratio of their partial pressures will be.....

frnds answer it with clear explanation plz........


no spams... ​

Answer 1

Answer:

N2O

Explanation:

two atoms of nitrogen and one atom of oxygen so it will be N2 +o=N2O

Answer 2

Answer:

The ratio of partial pressures is 16:7

Explanation:

Partial Pressure of  $N_{2}$ given by $\left(\frac{n N_{2}}{n T}\right) \times P_{t o t a l}$

Partial Pressure of $\boldsymbol{O}_{2}$ is given by$\left(\frac{n O_{2}}{n T}\right) \times P_{\text {total}}$

Therefore the ratio of partial pressures will be  $\frac{n N_{2}}{n O_{2}}$

=$\left(\frac{m N_{2}}{M N_{2}}\right) \times\left(\frac{M O_{2}}{M O_{2}}\right)$

$=\left(\frac{2}{28}\right) \times\left(\frac{32}{1}\right)$

$=\left(\frac{32}{14}\right)$

$=\frac{16}{7}$

Therefore the ratio is 16:7.
