I wanted to know the units or if the units I put on the table is right. For example the unit for mass of solid or the unit for volume of water

Answer
All the units were correct.
The unit of part b can either be any of milliliter or cubic centimeter
Density = 12446.71 g/mL
Explanation
All the units were correct.
Note:
1 milliliter = 1 cubic centimeter
g = grams
mL = milliLiter
The unit of part b can either be any of milliliter or cubic centimeter
The unit of the mass is g
The unit of the volume is mL
The unit of density is g/mL
The density of the solid = mass/volume = 87127/7 = 12446.71 g/mL
