Question

A solution contains 50g of common
salt in 200g of water. Calculate the
mass by mass % of the solution?​

Answer 1

Answer:

its 20%

Explanation:

mass %=mass of solute /mass of solution ×100

therefore,its 50/200+50 ×100 which is 20%..hope it helped :)..mark me brainliest of you found this helpful :)

Answer 2

Given:

• Mass of common salt (solute) = 50g
• Mass of water (solvent) = 200g

_________________________________

To find:

Concentration of the solution (mass by mass percentage).

_________________________________

Solution:

We are given that,

Mass of common salt (solute) = 50g

Mass of water (solvent) = 200g

So,

Total mass of solution = mass of solute + mass of solvent

⇒ (50+200) g

Mass of solution = 250g

Now, we know that,

$\sf \dfrac{Mass\ of\ solute}{Mass\ of\ solution} \times 100$

Substitute the values in the formula,

⇒ $\sf \dfrac{50}{250} \times 100$

⇒ $\sf \dfrac{1}{5} \times 100$

⇒ $\boxed {\sf {\purple {20 \%}}}$

Final answer:

Hence, the mass by mass concentration of the solution is 20%.
