Question

Genna threw 45 grams of sugar into 55 grams of water. She made ___ grams of ___% sugar syrup.

Answer 1

45+55=100 so that means 100 grams of the substance was made because percentages go up to 100 and she made 100 grams, we know that the substance, in this case syrup is 45% sugar

Answer 2

She made She made 100 grams of 45% sugar syrup.

Explanation:

Genna added 45 grams of sugar into 55 grams of water.

Total amount she mixes = 45 + 55 = 100 grams.

Percentage of sugar in total mixture (sugar syrup) = 45 grams sugar in 55 grams syrup.

`\text{\% by mass}=\frac{\text{mass of solute}}{\text{(mass of solute + mass of solvent)}} * 100`

Here, Solute is sugar and Solvent is water.

mass of solute = 45

mass of solute + mass of solvent = 100

Putting values, we get,

`\text{\% by mass}=(45)/(100) * 100`

`\text{\% by mass}=45\%`

Thus, She made She made 100 grams of 45% sugar syrup.
