What is the concentration of a solution that has a volume of 2.5L and contains exactly 2.125 moles of calcium phosphate
Iteru [2.4K]

Answer:

0.85 mol/L.

Explanation:

  • Molarity is defined as the no. of moles of solute dissolved in a liter of the solution.

<em>M = (no. of moles of solute)/(Volume of the solution (L))</em>

no. of moles of calcium phosphate = 2.125 mol.

Volume of the solution = 2.5 L.

<em>∴ M of calcium phosphate</em> = (2.125 mol)/(2.5 L) = <em>0.85 mol/L.</em>
