Question

What is the volume of a rock if it has a density of 1.25g/ml if it has a mass of 7525g?

Answer 1

V = 6020

Explanation:

will make it sure and simple

formula of density d = mass / volume

where d = 1.25 g/mL

and mass = 7525 g

plugin values into the formula

1.25 = 7525 / Vol

Vol = 7525 / 1.25

Vol = 6020

Answer 2

`\boxed{\tt v= 6,020 \ mL}`

Explanation:

The density formula is

`d=(m)/(v)`

Rearrange the formula for v. Multiply both sides of the formula by v, then divide both sides by d.

`d*v=(m)/(v)*v`

`d*v=m`

`(dv)/(d)=(m)/(d)`

`v=(m)/(d)`

The volume can be found by dividing the mass by the density. The mass is 7525 grams and the density is 1.25 grams per milliliter.

`m= 7525 \ g\\d=1.25 \ g/mL`

`v=(m)/(d)`

`v=(7525\ g)/(1.25\ g/mL)`

Divide. Note that the grams, or "g" will cancel each other out.

`v=(7525 \ )/(1.25\ mL)`

`v=6020 \ mL`

The volume of the rock is 6,020 milliliters.
