Question

Find the total pressure for a mixture that contains three gases with partial

pressures of 5.00 kPa, 4.56 kPa, and 1.20 kPa?

Answer 1

Dalton's Law: The total pressure exerted by a gas mixture is the sum of the pressure exerted by the individual components present in the mixture.

Hence

$P_T=P_a+P_b+P_c$

$P_T=5+4.56+1.20=10.76kPa$
