Ella has 0.5 lbs of sugar. How much water should she add to make the following concentrations? Tell Ella how much syrup she will have in each case.


75% syrup?

Respuesta :

Ella has 0.5 lbs of sugar. 75% syrup

Percent of mass = [tex] \frac{mass of solute}{mass of solution} * 100 [/tex]

Let the mass of solution is x

Given mass of solute = 0.5

percent of mass = 75

75 = [tex] \frac{ 0.5}{x} * 100 [/tex]

75x = 0.5 * 100

75 x = 50

x = 0.67

Mass of solution = 0.67

Mass of water = mass of solution - mass of solute (sugar)

= 0.67 - 0.5 = 0.17

So 0.17lb of water is added with 0.5lb of sugar to get 0.67lb of solution.
