Given the following reaction:

H2SO4 + 2LiOH - -> Li2SO4 + 2H2O

What mass of water is produced from 19 g of sulfuric acid?

Question options:

1.0

7.0

2.0

6.3

Approx. 4⋅g.

Explanation:

Moles of sulfuric acid = 10.0⋅g98.08⋅g⋅mol-1=0.102⋅mol.

Now we have the molar quantity of sulfuric acid that react; we also have the stoichiometric equation that shows the molar equivalence of sulfuric acid, and lithium hydroxide.

Given the stoichiometry,

mass of water = 0.102⋅mol*2*18.01. g. mol-1=?⋅g.

Why did I multiply the mass in this equation by 2? Am I pulling your leg?
