Answer:

0.85 M

Explanation:

Step 1: Given data

  • Mass of calcium phosphate (m): 660 g
  • Volume of solution: 2.5 L
  • Molar mass of calcium phosphate (M): 310.18 g/mol

Step 2: Calculate the moles (n) corresponding to 660 g of calcium phosphate (solute)

We will use the following expression.

n = m/M

n = 660 g/(310.18 g/mol) = 2.13 mol

Step 3: Calculate the molar concentration (molarity) of the solution

Molarity is equal to the moles of solute divided by the liters of solution.

M = 2.13 mol/2.5 L = 0.85 M
