Genna threw 45 grams of sugar into 55 grams of water. She made ___ grams of ___% sugar syrup.
OlgaM077 [116]

Answer:

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

Step-by-step explanation:

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

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

mass of solute = 45
