Question

A solution of water and alcohol contains 30g of water and 60g of alcohol what is the concentration of solution​

Answer 1

Answer:

water =30 g

alcohol=60 g

mass of solution = mass of water + mass of alcohol

30 g +60 g

90g

concentration of solution = mass of solute / mass of solution ×100

= 30 /90 ×100

=0.333

is the concentration of solution

Answer 2

Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.

given,

water =30 g

alcohol=60 g

mass of solution = mass of water + mass of alcohol

=30 g +60 g

=90g

concentration of solution = mass of solute / mass of solution ×100

= 30 /90 ×100

=0.333

is the concentration of solution
