The density of a substance with a mass of 48 grams and a volume of 3 ml is what

P = m/v

Where P is the density,

m is the mass (in g), and

v is the volume (in L)

P = m/v

= (48 g) (0.003L)

= 0.144 g/L

Significan figures count too.

48 g has two significant figures

0.003L has to only one significant figure. Therefore, the answer will have only 1 significant figures.

Our final answer will be 0.1g/L
