Question

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

16.56 g
8.76 g
2.17 g
0.46 g

Answer 1

d = m/v
m = dv
m = 2.76 g/cm3 x 6 cm3
m = 16.56 g

Answer 2

`16.56\ g`

Explanation:

we know that

The density is equal to the mass divided by the volume

Let

x-----> the mass of marble

y----> the volume of marble

z----> the density of marble

`z=(x)/(y)`

in this problem we have

`y=6\ cm^(3)`

`z=2.76\ g/cm^(3)`

substitute and solve for x

`2.76=(x)/(6)`

`x=2.76*6=16.56\ g`
