Question

Pumice is a volcanic rock that contains many trapped air bubbles. A 225- gram sample is occupied 236.6ml.

a. What is the density of pumice (answer is 0.951g/ml)

Answer 1

`{\boxed{{ formula :}}}`

`→\bold{Density = (mass)/(volume) }`

`{\boxed{{ Given :}}}`

`→\bold{Mass = 225 g }`

`→\bold{ Volume = 236.6 ml}`

`{\boxed{{ Solution :}}}`

`→\bold{Density = (mass)/(volume) }`

`→\bold{ Density = \cancel{ (225 g)/(236.6 ml)} = 0.951 g/ml}`

The density of pumice is 0.951 g/ ml .

Answer 2

to find:

density of the pumice.

solution:

density= mass/ volume (d= m/v)

= 225/236.6

= 0.951g/ml

so, the density of pumice is 0.951g/ml.
