Question

the concentration of the salt solution in term of mass by mass percentage is 20% and the mass of the solution is 550 gram determine the mass of solute present in the solution

Answer 1

Hey mate !!

Here's the answer !!

We know that, 

Concentration of solution = Mass of solute / Mass of solution * 100%

Given that Concentration = 20%, Mass of solution = 550 g.

We need to find Mass of solute = ?

Substituting in the formula we get, 

20% = Mass of solute / 550 g * 100%

=> 20 % * 550 g / 100 % = Mass of solute

=> 11000 g / 100 = Mass of solute

=> 110 g = Mass of solute.

Hence Mass of solute = 110 g

Hope my answer helped !!

Cheers !!
