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

There are different ways to
express concentrations. The most
common ones include
i. Molarity, and
ii. Percent
(mass/mass)
iii. Parts per million
(ppm).
To understand the definition of
these units, perform the following
task. Provided that we can
determine the amount of a
substance of interest (let's say
compound X) in grams, show the
equations for the calculations of
the molarity and ppm of X in a
given amount of aqueous sample.
