Read each question carefully and show all your work for conversion problems. Use appropriate units and significant figures.
1. Convert 2.5 kilograms to grams.
2. How many milliliters are in 0.75 liters?
3. The number 0.0050 has significant figures.
4. When multiplying 2.34 cm by 1.2 cm, the answer should have significant figures.
5. What is the molar mass of water (H₂O)? (Atomic masses: H=1.01 g/mol, O=16.00 g/mol)
17.01 g/mol
18.02 g/mol
19.01 g/mol
20.00 g/mol
6. How many moles are in 36.04 grams of water (H₂O)?
1 mole
2 moles
3 moles
4 moles
7. Consider the reaction: 2H₂ + O₂ → 2H₂O. If you start with 4 moles of H₂, how many moles of H₂O can be produced?

8. Using the same reaction, if 32.00 grams of O₂ react completely, what mass of H₂O is produced?
