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)?
