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

1/4 ml

Explanation:

Density=8g/ml

Mass=2g

Volume=mass/density

Volume=2/8

Volume=1/4 ml

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.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
