Find the volume of an object that has a density of 3.14 g/mL and a mass of 52.9 g.
Natasha_Volkova [10]

Answer:

The answer is

<h2>16.8 mL</h2>

Explanation:

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

volume =  \frac{mass}{density}  \\

From the question

mass of object = 52.9 g

density = 3.14 g/mL

The volume of the object is

volume =  \frac{52.9}{3.14}  \\   = 16.847133757...

We have the final answer as

<h3>16.8 mL</h3>

Hope this helps you

O They all have the same number of atomst

a mole of anything contains Avogadros number of 6.022X10^23  things

which has the greatest number of thing? a dozen eggs, a dozen cookies, a dozen pizzas?

a dozen is a number means 12

a mole is a number that that means 6.022 X 10^23 you calculate the molar mass from the chemical formula, but every j mole contains 6.022X10^23

particles.

just like every dozen contains 12

so

They all have the same number of atoms
