<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:
.....(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:
Hence, the molarity of KBr solution is 0.605 M
