If you had 4moles of oxygen atoms, how many molecules of sodium carbonate can you make?

Question

thomaster · Answer

The molecular formula of sodium carbonate is $\sf Na_2CO_3$
So 1 molecule of sodium carbonate contains 3 oxygen atoms.

The only think you have to do is calculate how many oxygen atoms you have, and divide that by 3.
To calculate how many oxygen atoms you have, multiply the number of moles oxygen (4 in this case) by Avogadro's number ( $\sf6.022*10^{23}$)

I added a diagram which explains how to convert these things, you start at mol and go to number of particles (atoms)

So just multiply 4 by avogadro's number and then divide that by 3 to get the amount of sodium carbonate molecules you can make with 4 mol oxygen.

Hope this helps :)
