Question

Find the molarity of a solution made by dissolving 12.5 g sodium carbonate in 500.0 mL total solution

Answer 1

Answer:

The molarity of a solution is "25 M".

Explanation:

The given values are:

Moles of solute,

= 12.5 g

Volume of solution,

= 500 mL

i.e.,

= 0.5 L

Now,

The molarity will be:

=  $\frac{Number \ of \ moles \ of \ solute}{Volume \ of \ solution}$

On substituting the values, we get

=  $\frac{12.5}{0.5}$

=  $25 \ M$
