6. Calculate the densities of the liquids in Table 2.3. The accepted density of water is 1 g/ cm3. How do your results compare? Remember that 1 cm3 = 1 mL. 7. How does the density of water compare with the density of the saturated salt solution? Is this what you would have predicted? 8. Length of room m 9. Width of room m 4.02 3.37 10. Height of room m 11. Volume of room m3 12. Mass of air in room kg 13. Are you surprised by the mass of air in the room? Explain.

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
