Question

rock with a mass of 70 grams is dropped into a graduated cylinder with 30 mL of water. The water level rose. Whats the density of the rock in g/mL.

Answer 1

The density of the rock in g/mL : 14 g/ml

Complete question :

A rock with a mass of 70 grams is dropped into a graduated cylinder with 30 mL of water in it. The water level rose to 35 mL calculate the density of the rock in g/mL

Further explanation

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

Density formula:

`\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}`

ρ = density

m = mass

v = volume

mass of rock = 70 g

Volume of the rock : 35 - 30 = 5 ml

So the density :

`\tt \rho=(70)/(5)\\\\\rho=14~g/ml`
