400 ml of hydrogen are collected over water at 18 c and a total pressure of 740 mm of mercury. (vapor pressure of h2o at 18 c=15.5mm).

a) what is the partial pressure of h2o?

b) what is the partial pressure of h2?

there all right good

explanation:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
