Sodium carbonate (naco3) is sometimes used as a water-softening agent. suppose that a worker prepares a 0.730 m solution of naco3 and water. the volume of the solution is 1.421 liters. what is the mass of solute in the solution?

The molarity of a solution is the number of moles of a substance divided by the volume in liters prepared.

, where n is number of moles and V is the volume in liters.

In order to calculate the mass of solute we need to convert the volume and molarity to moles

Now that we have moles we use the relative formula mass of NaCO₃, We have 1 Na atom, 1 C atom and 3 O atoms, thus

quartz
