All answers are to be in decimal form (not scientific notation). All answers need to be rounded to the correct number of significant digits.
1. A rock with a density of 4.56 g/mL and a mass of 3.45 g has what volume? (0.757 mL)
2. A rock with a mass of 4.59 g and a volume of 5.78mL has what density? (0.794 g/mL)
3. A rock with a volume of 10.0 mL and a density of 3.87 g/mL has what mass? (38.7 g)
4. A marble with a density of 8.93 g/mL and a mass of 9.00 g has what volume? (1.01 mL)
5. A marble with a volume of 80.9 mL and a density of 1.90 g/mL has what mass? (154 g)
6. A boat with a mass of 9.04 x 105 Kg and a volume of 8.90 x 107 mL has what density (notice that you will have to convert Kg into grams before beginning this problem). (10.2 g/mL)
7. A styrofoam ball with a density of 1.05 g/L and a volume of 5.90 mL will have what mass? (notice that you will have to convert g/L into g/mL before beginning this problem). (0.00620 g – that’s 3 sig figs)
8. A computer monitor with a density of 89.0 Kg/mL and a volume of 5.00 L will have what mass? (notice that Kg/mL will have to be converted to g/mL and volume will need to be converted to mL before beginning this problem.) (445,000,000 g or 4.45 x 108g)
9. A stapler with a mass of 3.48 Kg and a density of 9.00 g/L will have what volume?
(387,000 mL or 3.87 x 105mL)
10. A watch with a mass of 0.09 Kg and a volume of 18.0 mL will have what Density? (5 g/mL)
1 L = 1 dm3
1 L = 1000 mL
1mL = 1 cm3
