You have 3 l of a 5m solution of calcium chloride. how many l would you be able to make of a 0.5m solution?

30.0 L.

Explanation:

(MV)before dilution = (MV)after dilution

M before dilution = 5.0 M, V before dilution = 3.0 L.

M after dilution = 0.5 M, V after dilution = ??? L.

∵ (MV)before dilution = (MV)after dilution

∴ (5.0 M)(3.0 L) = (0.5 M)(V after dilution)

∴ V after dilution = (5.0 M)(3.0 L)/(0.5 M) = 30.0 L.
