Question

The amount and the concentration of a salt solution is given. How much salt would you get if you evaporated all water from this solution? 450g of a 9% solution

Answer 1

40.5g

Explanation:

RSM anyone?

Answer 2

40.5 g

Explanation:

Find how much salt is in 450 g of a 9% salt solution.

Note that

450 g - 100%,

x g - 9%,

then

`(450)/(x)=(100)/(9),\\ \\x=(450\cdot 9)/(100)=40.5\ g.`

If you evaporated all water from this solution, then you would get 40.5 g of salt.
