Question

A student dissolves 45.2 G of MG oh H2 in enough water to make 1.00 L of solution the concentration of the solution is.

Answer 1

Obviously it's 45.2 g Mg(OH)2/L of solution. But if you want it in terms of molarity it is 45.2/molar mass Mg(OH)2 in 1 L = ? M. If if in terms of normality it is 45.2g/equivalent mass Mg(OH)2 in 1 L = ? N
