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

Answer:

The answer is 0.6923 mL

Explanation:

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

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

Making volume the subject we have

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

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

$volume = \frac{5.040}{728} \\ = 0.692307$

We have the final answer as

Volume of nickel = 0.6923 mL

Hope this helps you
