Convert moles to atoms?

Award the best answer if you can answer the following with steps:


1. 8.15 moles of Mg


2. 21.3 moles of I2


3. 2.34 moles of Na2CO3





*Note that I2 where 2 is a subscript also Na2 and CO3

Convert moles to atoms?
1 mole = 6.02 * 10^23 atoms


literally multiply through bro...


1) 8.15 moles of Mg


(6.02 * 10^23) * 8.15 =


4.9063 * 10^24 atoms





2) 21.3 moles of I2


(6.02 * 10^23) * 21.3 = 1.28226 * 10^25 MOLECULES (because I2 is a molecule) Multiply by 2 to get atoms...


2(1.28226 * 10^25) =


2.56452 * 10^25 atoms





3) 2.34 moles of Na2CO3


(6.02 * 10^23) * 2.34 = 1.40868 * 10^24 molecules


In each molecule, there are 2 Na, 1 C, 3 O = 6 atoms


Multiply by 6


1.40868 * 10^24 =


8.45208 * 10^24 atoms





Tada..hope this was thorough enough


hard to type out the numbers
