Question

3. What is the total pressure of a mixture of nitrogen and hydrogen, in atm, if the

partial pressure of nitrogen is 509.7 mmHg and the partial pressure of hydrogen is
630.3 mmHg?

Answer 1

As per Dalton's law of Partial pressure,

The total pressure of a mixture of gases is equal to sum of partial pressure of individual components of the mixture.

So, P=P_H+P_N+P_WP=P

H

​

+P

N

​

+P

W

​

\implies 864\ mm=220\ mm+410\ mm+P_W\implies⟹864 mm=220 mm+410 mm+P

W

​

⟹ P_W=864-630=234P

W

​

=864−630=234 mm of Hg.
