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

36.3 mL
1.43 mL

Explanation:

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

Making volume the subject we have

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

We have the final answer as

Hope this helps you

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
