********Chemistry Help for Medal ********
What mass of H2O is produced from 100 g of H2 in the foillowing reaction. 2H2 + O2 → 2H2O
Select one:
a. 900 g H2O
b. 600 g H2O
c. 200 g H2O
d. 300 g H2O

Answer 2

I feel like the answer is D.)

Answer 3

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

Answer 4

@EmazingEm3399 Good with this now?

Answer 5

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

Answer 6

@dtan5457

Answer 7

Molar ratio is 1:1

100g H2/2g per mol = 50mols 50mols

18g per mol = 900g H2O

Answer 8

Looks good :)

Answer 9

Thanks Dan!
