Question #0bf2d

Answer 1

`"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"`
