# Given the equation: LiOH + HBr --> LiBr + H2O. If you start with ten grams of lithium hydroxide, how many grams of lithium bromide will be produced?

##### 1 Answer

#### Answer:

Ten grams of LiOH will produce

#### Explanation:

**Molar Masses of LiOH and LiBr**

To complete this problem, we are going to go from mass LiOH to moles LiOH to moles LiBr to mass LiBr.

**Mass LiOH to Moles LiOH**

Since you didn't give a numeric value for ten grams, it will be written as

**Mole LiOH to Mole LiBr**

Multiply the mol LiOH times the mole ratio between LiBr and LiOH in the balanced equation, so that LiBr is in the numerator and LiOH is in the denominator so it will cancel.

**Mole LiBr to Mass LiBr**

Multiply the mol LiBr times the molar mass of LiBr.
