Most likely to be found is called an Orbital.
Answer:
<h3>The answer is 0.622 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass = 12 g
density = 19.30 g/mL
We have

We have the final answer as
<h3>0.622 mL</h3>
Hope this helps you
Explanation:
TO calculate emperical formula , we need percentage composition of the elements and molecular mass of a specific compound which is already given in the question
then create a table with 1.name of element, 2.percentage given and its atomic mass , 3.no. of moles
( %given/at.mass of element) ... then take the least value in the no. of moles you have found now and divide with each no. of moles value .. to get a simple digit number.
You have got the empirical formula
