Question

a solution has 42g of copper sulphate in 528g of water. calculate the concentration in terms of mass by percentage of the solution​

Answer 1

Answer:

Explanation:

copper sulphate(solute)=42g

water=  528g

solution=528+42

=570g

mass  of solute/mass  of solution

=42/570

0.073

Answer 2

Question:-

A solution has 42g of copper sulphate in 528g of water. calculate the concentration in terms of mass by percentage of the solution.

Given data:-

Let, copper sulphate be the solute and

water be the solvent.

—› Mass of solute = 42 g

—› Mass of Solvent = 528 g

Solution:-

{To find concentration in term of mass by percentage of the solution}

Here we know,

—› Solution = Solute + Solvent

Hence,

—› Mass of solution

= Mass of solute + Mass of solvent

—› Mass of solution = 42 + 528

—› Mass of solution = 570 g

Now, we use formula to find concentration of solution.

—› Concentration of solution

= [Mass of solute/Mass of solution]×100%

—› Concentration of solution

= [42/570]×100%

—› Concentration of solution

= [7/95]×100%

—› Concentration of solution

= 0.073684×100%

—› Concentration of solution

= 7.3684 %

Hence, the concentraction of the solution is 7.3684 %
