It look straight forward to me. I'll do one of them.

2 mols K + 2 mols H2O yield 2 mols KOH and 1 mol H2.

Now you can do the masses.

2*atomic mass K = 78 g K combine with 2*18 or 36 g H2O etc.

mols = M x L. You know M and L, solve for mols.

Then mol = grams/molar mass.

You know mols and molar mass, solve for grams.
