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

Answer:

$16.56\ g$

Step-by-step 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

$z=\frac{x}{y}$

in this problem we have

$y=6\ cm^{3}$

$z=2.76\ g/cm^{3}$

substitute and solve for x

$2.76=\frac{x}{6}$

$x=2.76*6=16.56\ g$
