The solution contains 75 grams of water and 6 grams of salt, what percentage is the mass of salt

The solution contains 75 grams of water and 6 grams of salt, what percentage is the mass of salt from the mass of water in the solution.

Brief notation of the problem condition:

Water – 75 g;

Salt – 6 g;

% salt in water?

Solution:

To find how many percent is the mass of salt from the mass of water in solution, you need to determine how many percent is the number 6 of the number 75.

To express one number as a percentage of another, you need to multiply the first number by 100 and divide the result by the second number.

Then:

6 * 100: 75 = 6 * 4/3 = 2 * 4 = 8 (%);

Answer: 8%.
