In an experiment, magnesium metal was dissolved in HCl and hydrogen gas was collected in an eudiometer. The hydrogen gas was mixed with water vapor. The mixture has a total pressure of 757 torrtorr , and the water vapor has a partial pressure of 23 torrtorr . What amount (in moles) of hydrogen gas is contained in 1.61 LL of this mixture at 298 KK?

Express the amount in moles to three significant figures.
