What is the molarity of a 750 milliliters solution containing 54.0 grams of KBr (help me please)
ololo11 [35]

<u>Answer:</u> The molarity of KBr solution is 0.605 M

<u>Explanation:</u>

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}\times 1000}{\text{Molar mass of solute}\times \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}=\frac{54.0\times 1000}{119\times 750}\\\\\text{Molarity of solution}=0.605M

Hence, the molarity of KBr solution is 0.605 M
