The chemical formula of water is written as H2O we can just use the ratio of the atoms since we are not given the reaction. Hydrogen is a diatomic substance so that it exists as H2. We calculate as follows:
0.253 mol H2O ( 1 mol H2 / 1 mol H2O ) = 0.253 H2 needed
Hope this answers the question. Have a nice day.

It's in group 1, so its outershell only has 1 electron, and the other shells are completely filled, so 2 then 8. :)
1 mol of Silicon = 28.0855 g (in average)
then
1 mol = 6.022*10^23 atoms
then
28.0855/(6.022*10^23) g/atom
4.66381*10^-23 g per atom
