Na + H2O ¨ NaOH + H2

How many moles of H2 would be formed from 30 grams of Na in the following (UNBALANCED) equation?

• chemistry -

2Na + 2H2O == 2NaOH + 2H2
mols Na = grams/atomic mass
Convert mols Na to mols H2 using the coefficients in the balanced equation. That's 2:2 therefore, mols H2 = mols Na.
