Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Question

Concentration is the amount of solute dissolved in a certain amount of solution:
amount of solute
concentration of a solution
amount of solution
Solution concentrations are usually given as one of the following:
Mass percent (m/m)–the mass of the solute in grams for exactly 100 g of solution
Volume percent (v/v)–the volume of solute in exactly 100 mL of solution
Mass/volume percent (m/v)–the mass of solute in grams for exactly 100 mL of solution
Molarity (M) – the number of moles of solute in exactly 1 L of solution
Part A
Calculate the mass percent (m/m) of a solution prepared by dissolving 56.79
of NaCl in 155.2 g of H2O.
