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

Respuesta :

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

Answer:

[tex]16.56\ g[/tex]

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

[tex]z=\frac{x}{y}[/tex]

in this problem we have

[tex]y=6\ cm^{3}[/tex]

[tex]z=2.76\ g/cm^{3}[/tex]

substitute and solve for x

[tex]2.76=\frac{x}{6}[/tex]

[tex]x=2.76*6=16.56\ g[/tex]
