Question

The density of a nickel coin was determined by laboratory measurement to be 728 g/mL. A nickel has a mass of 5.040 grams. What is the volume of the nickel?

0.6923 mL
0.692 ml
оооо
36.3 mL
1.43 mL

Answer 1

The answer would be 0.6923 mL :)

Answer 2

The answer is 0.6923 mL

Step-by-step explanation:

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

`Density = (mass)/(volume)`

Making volume the subject we have

`volume = (mass)/(Density)`

From the question

Density = 728 g/mL

mass of nickel = 5.040 g

Substitute the values into the above formula and solve for the volume

That's

`volume = (5.040)/(728) \\ = 0.692307`

We have the final answer as

Volume of nickel = 0.6923 mL

Hope this helps you
