75.23 grams of Ba3(PO4)2 is how many Ba atoms? are they just asking how many molecules there are? but i still dont get how to solve it. i know its .1619 moles but that might not be helpful information

Question

anonymous · Answer

how many molecules are in a mol?  Just multiply that by 0.1619

anonymous · Answer

6.02 X 10^23

anonymous · Answer

but that only solves the number of molecules of ba3(po4)2. So you know it takes 3 ba atoms to make one molecule

anonymous · Answer

give me a sec i will set up the factor label solution

anonymous · Answer

wait the answer is just 3?

anonymous · Answer

No you have to multiple by 3.  So it's 0.1619 X 6.02E23 X 3 atoms/molecule

anonymous · Answer

once i find the amount of molecules should i multiply it by 3?

anonymous · Answer

ok thanks

anonymous · Answer

can i ask you another question?

anonymous · Answer

$$75.23 g Ba_3(po_4)_2 (\frac{1 mole}{})$$

whats the molar mass of that?

anonymous · Answer

its ok i figured it out. if u dont mind, can i ask you this question: how many molecules of C6H1206 contain 4.56 x 10^23 atoms of carbon?

anonymous · Answer

once again i would set up a factor label solution to solve this

anonymous · Answer

i dont know what that is

anonymous · Answer

I will set it up on the other post give me a min because it take a while to do

anonymous · Answer

ok please dont make it complicated i dont think its supposed to be hard

anonymous · Answer

i think you can just do some division, if there are six carbons in each molecule

anonymous · Answer

how do i do that

anonymous · Answer

divide number of atoms by 6

anonymous · Answer

thats all? 4.56E32 divided by 6?
