Question

Calculate the molarity of 11.6 cm³
of solution containing 0.750 g of Cacl2​

Answer 1

Answer:

Molarity of a solution is defined as number of moles of solute dissolved per liter of solution.

Molarity ( M) = # of moles of solute / volume of solution (L)

Volume of Solution = 100 mL or 0.1 L
