Question

If the density of an object is 5 g/cm3 and it takes up 7 cm3 of space, calculate the mass?

A) 35g
B) 5g
C) 7g
D) 1.4g

Answer 1

The answer is option A

Step-by-step explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume of object = 7 cm³

density = 5 g/cm³

The mass of the object is

mass = 5 × 7

We have the final answer as

35 g
