Question

what is the concentration of a solution containing 12g of solute and 188g of solvent in terms of mass by mass percentage?​

Answer 1

Answer:

Mass % =

Mass of solution

Mass of solute×100

=

110

10×100

=9.09=9.1%

Answer 2

Given,

Mass of the solute = 12 g

Mass of the solvent = 188 g

To find,

Concentration of the solution in terms of mass by mass percentage.

Solution,

We can simply solve this numerical problem by using the following process.

First of all, we need to calculate the mass of the whole solution.

Mass of the solution :

= Mass of the solute + Mass of the solvent

= (12+188) g

= 200 g

Now,

Mass by mass percentage of a solution = (Mass of the solute / Mass of the solution) × 100%

By, putting the given values, we get,

Mass by mass percentage of the solution = (12/200) × 100% = 6%

Hence, concentration of the solution in terms of mass by mass percentage is 6%
