Here's how to calculate the molarity of the CaBr₂ solution:

Understanding Molarity

Molarity (M) is a unit of concentration that represents the number of moles of solute dissolved in one liter of solution. The formula is:

Molarity (M) = moles of solute / liters of solution

Calculations

1. Convert mL to L:

750.0 mL * (1 L / 1000 mL) = 0.750 L

2. Apply the Molarity Formula:

Molarity (M) = 1.50 mol / 0.750 L = 2.00 M

Answer: The molarity of the CaBr₂ solution is 2.00 M.
