In a lab experiment which was done with a barometric pressure of 1.043 atm, some H2 was measured over water at 27.0°C to have a partial pressure of 0.035 atm . What is the partial pressure of the "dry" H2 in the container?

1.008 atm

Explanation:

From the question given above, the following data were obtained:

Total pressure (Pₜ) = 1.043 atm

Partial pressure of H₂ over Water (Pᵥᵥ) = 0.035 atm

Partial pressure of dry H₂ (Pₔ) =?

The partial pressure of dry H₂ in the container can be obtained as shown below:

Pₜ = Pₔ + Pᵥᵥ

1.043 = Pₔ + 0.035

Collect like terms

1.043 – 0.035 = Pₔ

Pₔ = 1.008 atm

Thus, partial pressure of dry H₂ in the container is 1.008 atm

answerlinnaeus;

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
