Question

A sample of a substance has a mass of 4.2 grams and a volume of 6 milliliters. The density of this substance is
grams/milliliter.

Answer 1

Hello!

Mass =4.2 g

Volume =6 mL

Therefore:

Density = mass / volume

Density = 4.2 / 6

Density = 0.7 g/mL

Hope that helps!

Answer 2

Answer:

Density of the given substance is 0.7 grams/mL

Explanation:

Density is equal to $\frac{mass}{volume}$

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

So density = $\frac{4.2 g}{6 mL}=0.7 g/mL$

Here final answer should contain one significant figure.
