Answer: The molarity of KBr solution is 0.605 M

Step-by-step explanation:

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L.

The formula used to calculate molarity:


\text{Molarity of solution}=\frac{\text{Given mass of solute}* 1000}{\text{Molar mass of solute}* \text{Volume of solution (mL)}} .....(1)

Given values:

Given mass of KBr = 54.0 g

Molar mass of KBr = 119 g/mol

Volume of the solution = 750 mL

Putting values in equation 1, we get:


\text{Molarity of solution}=(54.0* 1000)/(119* 750)\\\\\text{Molarity of solution}=0.605M

Hence, the molarity of KBr solution is 0.605 M
