Question

If a 10mL object has a density of 1.5g/mL, what would its mass be (in g)?

Answer 1

15 g

Step-by-step explanation:

The density of an object can be found using the following formula:

`d=(m)/(v)`

We want to find the mass, so we must rearrange the formula for
`m`. Multiply both sides of the formula by
`v`.

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

`d*v=m`

The mass can be found by multiplying the density and volume.

The density of the object is 1.5 g/mL and the volume is 10 mL.

`d=1.5 g/mL \\v=10 mL`

Substitute the values into the formula.

`m=d*v`

`m=1.5 g/mL * 10 mL`

Multiply. When multiplying, the milliliters, or mL will cancel out.

`m= 1.5 g*10`

`m=15 g`

The mass of the object is 15 grams.
