I feel like the answer is D.)

dtan5457 · Answer

Just gotta find the mole ratio.

If there is 100 grams of hydrogen..

2H2=4 grams, you need to multiply everything by 25.

50H20=18 x 50=your answer

@EmazingEm3399 Good with this now?

anonymous · Answer

I think so. Would the correct answer be A.) in this case?

Molar ratio is 1:1

100g H2/2g per mol = 50mols 50mols

18g per mol = 900g H2O
