Answer/Explanation:

movement can be cause by the intense heat in the earth's core, which causes molten rock in the mantle layer to move.  it moves in a pattern called 'convection cell' which can form when the warm material rises, then cools, and eventually sink down.  then the process repeats (cooled, warms up and rises.. etc..)

I hope this was what you were kinda looking for:) - T

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.
