Question

a solution contains 50 gram of common salt in 400 gram of water calculate the concentration in the terms of mass by mass percentage of the solution​

Answer 1

Answer:

Mass of solute = 50g

mass of solvent = 400g

mass of solution = 50 + 400 = 450g

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

mass by mass = 50/450 * 100

= 100/9

= 11.1%

mass by mass % = 11.1%

Therefore the concentration percentage is 11.1%.

Answer 2

The required concentration is 11.11%.

Given:

Mass of salt=50g

Mass of water=400g

To find:

The concentration of the solution in the terms of mass by mass percentage

Solution:

We will obtain the mass of the solution and then calculate the percentage of salt with respect to it.

The mass of solution=Mass of salt+mass of water

Using values,

=50+400

=450g

The required concentration=Mass of salt/Mass of solution×100

=50/450×100

=500/45

=100/9

=11.11%

Therefore, the required concentration is 11.11%.
