Question

a solution contains 50 gram of sugar in 350 gram of water calculate the concentration of solution in terms of mass by mass percentage of solution

Answer 1

mass of solute = 50g

mass of solvent = 350g

mass of solution = 50 + 350 = 400g

mass by mass% = mass of solute / mass of solution

mass by mass = 50/400 * 100

= 100/8

= 12.5%

mass by mass % = 12.5%

Answer 2

The concentration of the solution is 12.5% mass by mass.

Given:

Mass of sugar= 50g

Mass of water= 350g

To Find:

The concentration of the solution (mass by mass percentage)

Solution:

The composition of a solution mixture is represented by mass percent. It indicates the solute content (in grams) in 100g of solution.

We know that,

Mass of sugar= 50g

Mass of water= 350g

So, total mass of solution= 50g + 350g= 400g

$Mass Percentage =\frac{grams of solute}{grams of solution} X 100 Mass Percent$

So, the concentration of solution (mass by mass%) $=\frac{50}{400}X100= \frac{25}{2}$

                                                                                     = 12.5%

Therefore, the concentration of the solution is 12.5% mass by mass.
