What is the mass of an object with a density of 80 g/mL and a volume of 8.5 mL?

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

volume = 8.5 mL

density = 80 g/mL

We have

mass = 80 × 8.5

We have the final answer as

Hope this helps you

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
