Answer:

8.3334%

Explanation:

You have two masses. To find the percent of sodium chloride in water by mass, you divide the mass of NaCl by water. First, make both units the same. Easiest is to convert kg into g. 1.5kg = 1500g

125g NaCl/1500g H2O = 0.0833333333 ==> 8.3334%

The mass of dissolved sodium carbonate is 109 g of Na₂CO₃.

<h3>What is a solution ?</h3>

A solution consists of two elements , a solute and a solvent .

A solute is dissolved into solvent to make a solution.

The concentration of a solution is measure by Molarity , Molality , mass% etc.

It is given in the question that

sodium carbonate ( Na₂CO₃) is sometimes used as a water-softening agent

a worker prepares a 0.724 m solution of  Na₂CO₃ and water.

the volume of the solution is 1.421 liters.

Mass of dissolved sodium carbonate is grams =?

Concentration = 0.724 M

Volume = 1.421 liters

Molecular mass of  Na₂CO₃  = 106 g

The mass of the solute needs to be determined

Molarity = moles / volume\

moles = Molarity x volume

Substituting the values

moles = 0.724 x 1.421

moles = 1.029

1 mol of Na₂CO₃ means  106 gm of  Na₂CO₃

Then 1.029 moles will mean 1.029 * 106

109.07 gm

Therefore , the mass of dissolved sodium carbonate is 109 grams.
