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

For numbers 1-2, solute concentration is described in the
following? Use the following choices:
A. Molality
B. Molarity
C. Mole fraction
D. Percent by mass
E. Percent by volume
F. Parts per million
1. 0.250 moles of NaOH is present in 2.50 L of a solution
2. 70% Isopropyl alchohol solutions penetrate the cell
wall more completely which permeates the entire
cell, coagulates all proteins, and therefore the
microorganism dies.
