Question

Jeff has a density of 1000 g/mL and a volume of 25-mL. What is Jeff’s mass?

Answer 1

25,000 grams

Explanation:

Density can be found using the following formula:

`d=(m)/(v)`

If we rearrange the formula for
`m`, mass, we will multiply both sides of the equation by v.

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

`d*v=m`

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

Jeff's density is 1000 grams per milliliter and his volume is 25 milliliters.

`d= 1000 g/mL\\v=25 mL`

Substitute the values into the formula.

`m=d*v`

`m= 1000 g/mL * 25 mL`

Multiply. When you multiply, the "mL" or milliliters will cancel out.

`m= 1000 g * 25`

`m= 25000 g`

Jeff's mass is 25,000 grams.
