the pressure of a `1 : 4` mixture of dihydrogen and dioxygen enclosed in a vessel is one atmosphere. What would be the partial pressure of dioxygen ?

The pressure of 1 : 4 mixture of dioxygen and dinitrogen in a vessel is 1.5 atmosphere. What would be the partial pressure of dinitrogen in Nm^(-1) ?

The pressure of a mixture of dihydrogen and dioxygen enclosed in a vessel is one atmosphere. The mole ratio of dihydrogen to dioxygen in the vessel is 1:4. What would be the partial pressure of dihydrogen?

A mixture of dihydrogen and dioxygen at one bar pressure contains 20% by weight of dihydrogen. Calculate the partial pressure of dihydrogen.
