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

40.5g of salt is left after evaporating all the water.

Step-by-step explanation:

Here, 9% of 450g means that out of 450 gram of solution, 9% is the salt.

So, we need to calculate 9% of 450

i. e. 9% * 450 = 0.09 * 450 = 40.5g

Hence, 40.5 grams of salt is in 450 grams of solution.

i. e. 40.5g of salt is obtained after evaporating all the water from the solution.
