Question

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

Answer 1

Answer:

15 g

Explanation:

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

$d=\frac{m}{v}$

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

$d*v=\frac{m}{v}*v$

$d*v=m$

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.
