Read each question carefully and answer to the best of your ability. Show your work for calculations.
1. is the amount of matter in an object.
2. We can measure mass using a .
3. The standard unit for mass in science is the .
4. A rock has a mass of 30 grams and a volume of 10 cubic centimeters. Calculate its density. (Formula: Density = Mass / Volume)
5. In a chemical reaction, what happens to the total mass of the substances involved?
It increases
It decreases
It stays the same
It depends on the reaction
6. The Law of Conservation of Mass states that mass cannot be created or in a chemical reaction.
7. To follow this law, chemical equations must be .
8. If you have 2 hydrogen atoms (H) and 2 oxygen atoms (O) on one side of a reaction, how many of each must be on the other side?
9. Adding more water to a solution changes its density.
