Question

A block of iron has a mass of 150 g and a volume of 20 ml. What is the density of iron? *

Answer 1

M/V=d
150/20=7.5
Density= 7.5

Answer 2

Answer:

The answer is 7.50 g/mL

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume}$

From the question

mass of iron = 150 g

volume = 20 mL

We have

$density = \frac{150}{20} = \frac{15}{2}$

We have the final answer as

7.50 g/mL
