Question

The density of an object is .835 g/cm. If it's volume is 34 cm, what is the mass of the object?

Answer 1

We know, density = mass / volume
Here, d = .835 g / cm³
v = 34 cm³

Substitute their values, 
.835 = m / 34
m = 34 * .835
m = 28.39 g

In short, Your Answer would be Option C

Hope this helps!

Answer 2

the answe is 28.39 g/cm
