i only put things in parenthesis to make things work better in my brain
1st rock = 19.28 grams
2nd rock = 25.30 grams
3rd rock = 46.3 grams
Add 1st and 2nd rock to get the combined mass
19.28 + 25.30 = 44.58 combined mass of 1st and 2nd rock
Subtract:
3rd rock mass - combined mass of 1st and 2nd rock
46.30 - 44.58 = 1.72 grams
1.72 grams greater was the mass of the 3rd rock than the combined mass of the two rocks.
