Question

A sample of marble has a volume of 6 cm3 and a density of 2.76 g/cm3. What is its mass?

Answer 1

Answer:

16.56g

Explanation:

6*2.76=16.56...

Answer 2

Answer:

16.56 grams

Explanation:

The density can be found using the following formula:

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

If we rearrange the formula for m, the mass, we should multiply both sides by v.

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

$d*v=m$

The mass can be found by multiplying the density and the volume. The density is 2.76 grams per cubic centimeter. The volume is 6 cubic centimeters.

$d= 2.76 g/c^3\\v=6 cm^3$

Substitute the values into the formula.

$m= d*v$

$m= 2.76 g/cm^3 * 6 cm^3$

Multiply. When you multiply the 2 "cm^3" will cancel each other out.

$m= 2.76 g* 6$

$m= 16.56 g$

The mass of the marble is 16.56 grams.
