A rock has the density of 8g/ml. If the rocks mass is 2g what is the rocks volume?

Answer: Volume = 0.25 mL

Explanation: Density is expressed as mass of the object per unit volume. So derive for volume,

d = m / V

Volume is expressed as mass divided by density or V = m / d

V = 2 g / 8 g / mL

= 0.25 mL

Cancel out the unit in grams and the remaining unit is in mL.

Answer:1/4 ml

Explanation:

Density=8g/ml

Mass=2g

Volume=mass/density

Volume=2/8

Volume=1/4 ml
