Question

A train robber in a western movie steals two gold ingots, each of which has a volume of 1000. cm3. The density of gold is 19.3 g/cm3. What is the mass of the two ingots?

Answer 1

The mass of the two gold ingots is 38.6 kg

Step-by-step explanation:

Let's apply density formula to solve the question:

Density = Mass / Volume

Density . Volume = Mass

19.3 g/ cm³ . 1000 cm³ = 19300 g

This is the mass of 1 ingot, but we have 2.

19300 g + 19300 g = 38600 g

We can convert the mass from g to kg

38600 g. 1 kg / 1000 g = 38.6 kg
