Question

A piece of Granite rock has a mass of 15.5 g and a volume of 6.01 mL. What is its density?

Answer 1

Answer:

2.58 kg/ litre

Explanation:

density = mass/ volume

= 15.5/6.01 = 2.579

= 2.579 gm/ ml = 2.579 kg/ litre

Answer 2

Answer:

explanation: density= massVolume , i.e mass per unit volume, and it typically has units of g-ml-1 or g-mc -3. if your rock has volume of 4-ml and mass of 16-g ,then we can take the quotient, massVolume = 16-g4-ml =4-g-ml-1.

Explanation:

given – density of rock =4glml

mass = 16g

we know ,

density = mass

volume

volume = mass

density

=16 (cancel) 4

4 ( cancel ) =4ml
