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

Answer:

40.5 g

Step-by-step explanation:

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

Note that

450 g - 100%,

x g - 9%,

then

$\dfrac{450}{x}=\dfrac{100}{9},\\ \\x=\dfrac{450\cdot 9}{100}=40.5\ g.$

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