How many grams of water formed by reacting 2gm of H2 with 2gm of O2

Question

anonymous · Answer

@Abmon98 .... Bro any idea about this

abmon98 · Answer

H2+1/2O2--->H2O
2/2=1 moles 
2/32=0.0625 
use the limiting reagent which is oxygen, 0.0625*18=1.125 grams although iam not sure

anonymous · Answer

but the options are...A) 2gms B) 2.25gms C)4gms D) 4.5gms

abmon98 · Answer

iam sorru i didnt multiply the number of moles of oxygen by 2 because the ration 1/2:1

matt101 · Answer

The answer is B. It's true that oxygen is the limiting reagent, but you need to take the stoichiometric ratios into account when finding the mass produced.

1 H2O/ ½ O2 = x H2O / 0.0625 O2
x = 0.125

So you have 0.125 moles of H2O produced, which is 18 x 0.125 = 2.25 g.
