The volume of a 18.0% solution is 74.6 mL. The density of the solution is 1.336 g/mL. What is the mass of the solution?
Density = Mass / Volume
Mass = Density x Volume
Mass of solution = 1.336 g/mL x 74.6 mL = 99.67 g
You asked for mass of the solution (not mass of solute). Hence answer is upto this.
Additional information:
Assuming that it is a weight/weight percentage,
100 grams of solution will contain 18.0 grams of solute.
1 gram of solution will contain (18/100) grams of solute.
74.6 grams of solution will contain (18/100)(74.6) grams of solute.
74.6 grams of solution will contain 13.428 grams of solute.
If it is weight/volume percentage, then there will be 18.0 grams of
solute per 100 mL of solution. Weight/volume is not a true
percentage, but instead is a conversion factor.
Notice that the density of the solution isn't used when the
percentage is given as weight/volume.
