If 110 gram of copper sulphate is present in 550 gram of solution, calculate the concentration of solution. Also calculate the mass of water.
Answers
Answer:
percentage by mass = 20%
mass of water = 440gram
Explanation:
percentage by mass = mass of solute × 100 ÷ mass of solution
=> percentage by mass =(110/550) × 100
=> percentage by mass = 20%
mass of solution = mass of solute+ mass of solvent
=> mass of solvent = mass of solution - mass of solute
=> mass of water = 550 - 110 = 440gm
The concentration of solution is 20% .
Explanation :-
The mass by mass % is given as follows:-
Mass by mass % of a solution =
[ ( mass of solute / ( mass of solution ) ] × 100
Here, mass of solute is 110 g
So, the mass of solution is 550 g
Therefore , mass by mass % of solution =
( 110 × 100 ) / 550 g
= 20 % ( proved )
Mass of solution = mass of solute+ mass of solvent
→mass of solvent = mass of solution - mass of solute
→mass of water = 550 - 110 = 440 gm.
