# H_2SO_4 + 2LiOH -> Li_2SO_4 + 2H_2O What mass of water is produced from 10 g of sulfuric acid?

Approx. $4 \cdot g$.

#### Explanation:

$\text{Moles of sulfuric acid}$ $=$ $\frac{10.0 \cdot \cancel{g}}{98.08 \cdot \cancel{g} \cdot m o {l}^{-} 1} = 0.102 \cdot m o l .$

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, $\text{mass of water}$ $=$ 0.102*molxx2xx18.01*g*mol^-1=??*g.

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