can you help me with #7? #7 says "A substance enters into and is altered through the course of a chemical change. it is called a
___." pick one of these choices. The lines that are next to the words are already picked from #s 1, 2, 3, 4, 5,& 6. do not pick more than one answer pick one answer only. tap the image so you could see the full image. (What I'm talking about is science.)

Explanation:
Mass of fructose = 33.56 g
Mass of water = 18.88 g
Total mass of the solution = Mass of fructose + Mass of water = M
M = 33.56 g + 18.88 g =52.44 g
Volume of the solution = V = 40.00 mL
Density =
a) Density of the solution:
b) Molar mass of fructose = 180.16 g/mol
Moles of fructose =
Molar mass of water = 18.02 g/mol
Moles of water=
Mole fraction of fructose in this solution:
Mole fraction of water =
c) Average molar mass of of the solution:
=
d) Mass of 1 mole of solution = 42.50 g/mol
Density of the solution = 1.311 g/mL
d) Specific molar volume of the solution:
