Answer:

Number of moles = 0.116 mol

Explanation:

Given data:

Number of moles of potassium bromide = ?

Volume of solution = 68.5 mL

Molarity of solution = 1.65 M

Solution:

First of all we will convert the mL into L.

68.5 mL × 1 L /1000 mL

0.07 L

Molarity = Number of moles / Volume in litter

we will rearrange the formula:

Number of moles = molarity × volume in litter

Now we will put the values in formula:

Number of moles = 1.65 M ×0.07 L

Number of moles = 0.116 mol
