Question

Can someone please help me find the answers to these questions?

13. If a sample of 18 metal marbles has a total volume of 21.0 mL and a total mass of 20.7 grams, what is the density of the metal marbles?

14. If you measured a sample of 9 metal marbles instead of 18, what would happen to the density? Please explain your answer in complete sentences.
15. Would one of the metal marbles described in question thirteen sink or float when placed in a glass of water? Remember that the density of water is 1.00 g/mL.

Answer 1

13. If a sample of 18 metal marbles has a total volume of 21.0 mL and a total mass of 20.7 grams, what is the density of the metal marbles?
density = mass/ volume

14. If you measured a sample of 9 metal marbles instead of 18, what would happen to the density? Please explain your answer in complete sentences.
Density it is an intensive property of the matter

15. Would one of the metal marbles described in question thirteen sink or float when placed in a glass of water? Remember that the density of water is 1.00 g/mL.

anything with a density smaller than 1.00 g/ml will float in water
