Approx.

#### Explanation:

The pressures are additive by Dalton's Law of Partial Pressures: the pressure exerted by a gas in a gaseous mixture is the same as the pressure it would exert if it alone occupied the container. I could calculate the individual partial pressures, or simply calculate the pressure based on the COMBINED molar quantities:

Given what I have said, can you calculate the partial pressures,
