solute=40 g
solvent= 100 ml
solution=100+40=140
Concentration= solute/solution *100
40/140 *100=28.5%
solvent= 100 ml
solution=100+40=140
Concentration= solute/solution *100
40/140 *100=28.5%

Mass by volume percentage :
It is the mass of the solute dissolved in 100 ml solution.
The formula is as follows :
Mass by volume percentage = (Mass of solute in grams / Volume of the solution in ml) × 100%
Doing the substitution we have :
Mass of the solute = 40g
Volume of the solution = 100ml
= 40/100 × 100% = 40%
The mass by volume percentage is therefore given as 40%
