#"10.02 mol H"#

Explanation:

In one molecule of #"H"_2"O"#, there are two atoms of #"H"# and one atom of #"O"#.

Thus, in one mole of of #"H"_2"O"# (which is just #6.022 xx 10^23# molecules), there are two moles of #"H"# and one mole of #"O"#.

#"5.011" cancel("mol H"_2"O") xx ("2 mol H") / ("1" cancel("mol H"_2"O")) = "10.02 mol H"#
