We’re being asked to calculate the mass of CaCl2 (in g) needed to make 6.0 L of a 0.310 M CaCl2 solution.
Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters).
In other words:
A chemist wants to make 6.0 L of a 0.310 M CaCl2 solution.
What mass of CaCl2 (in g) should the chemist use?
