Question

The mass of a piece of iron is 39 g and its volume is 5 cm3. What is its

density?
A. 6.7 g/cm3
B. 9.2 g/cm3
o O
C. 34 g/cm3
D. 7.8 g/cm3
O

Answer 1

Step-by-step explanation:

To solve this question, we need to use the following formula:

d = m/V

where:

d = density

m = mass

V = volume

so:

d = 39/5

d = 7.8 g/cm^3

Answer: D. 7.8 g/cm^3
