A 0.2 M solution of NaCl contains ________ g of NaCl in 1 l of ________.
Maksim231197 [3]

Answer:

11.7 g in 1 L of water.

Explanation:

Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.

It is defined as mol/ L (number of moles per litre).

0,2 M means we have 0,2 mol/ L

In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol

\frac{1 mol NaCl}{58.443 g} = \frac{0.2 mol}{X g}

X= \frac{(0.2 mol x 58.433 g}{1 mol}

X= 11.69 g

The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.
