Question

what is the mass percent of a solution of 7.6 gram sucrose in 83.4 gram of water​

Answer 1

Mass percent =mass of sucrose/mass of solution. X100
So
=7.6g/83.4+7.6. X100
=8.3516%

Answer 2

Formula:

mass percentage = mass of solute/mass of solution ×100

Step-by-step explanation:

mass of solute=7.6 grams

mass of solution=mass of solute + mass of solvent

                          =7.6+83.4=91

mass of solute/mass of solution×100

7.6/91×100=8.351648
