Hello!

Mass =4.2 g

Volume =6 mL

Therefore:

Density = mass / volume

Density = 4.2 / 6

Density = 0.7 g/mL

Hope that helps!

Density of the given substance is 0.7 grams/mL

Explanation:

Density is equal to

Here mass of substance is 4.2 grams and volume of substance is 6 mL

So density =

Here final answer should contain one significant figure.
