Question

A solution is prepared by mixing of 30 gram of 25% solution and 40 gram of 40% solution by mass calculate the mass percentage of resulting solution

Answer 1

n chemistry, a solution is a homogeneous mixture of two things - a solute and the solvent that it's dissolved in. Concentration is a measure of how much solute is dissolved within the solvent. There are many reasons for calculating the concentration of a solution, but the chemistry involved is similar whether you're testing the chlorine level in a hot tub or performing life-saving analysis on a blood sample. This guide will teach a few of the basic fundamentals of solution chemistry, then walk you through the process of one of its common practical applications - aquarium maintenance.
