Question

The mass of a an object is 5 g. The volume of the object is 10 mL.
1) What is the density of the object?

2) If the denisty of water is 1.0 g/mL, will the object sink or float in water? Why?

Answer 1

help @samanthagreer

Answer 2

a density for some material is just how much stuff is there per some volume of space

they give you 5g in 10mL, usually you want it in a unit volume, so simplify the fraction to get grams per 1 mL

Answer 3

huh

Answer 4

density = mass / volume

Answer 5

1.04/5?

Answer 6

density = 5g / 10mL = 1/2g / mL or 0.5 g/mL

Answer 7

huh?

Answer 8

5g/10ml=500kg

Answer 9

water is 1gram per cm^3, the larger the number the heavier it is for a given amount, so that would be expected to stay on top of the water, it is less dense

Answer 10

is that the answer?
