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?

80g of a 35% solution

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?

im really desperate, i will make you brainliest if u answer both of them correctly
20g of a 17% solution

Step-by-step explanation:

These problems only make sense if the percentage is by weight. To find the amount of salt, multiply the amount of solution by the percentage that is salt:

a) (80 g)(35%) = 28 g . . . . weight of salt

__

b) (20 g)(17%) = 3.4 g . . . . weight of salt

Comment on percent

You know that % means /100, so 35% = 35/100 = 0.35.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
