Question

diphosphorus pentoxide is P2O5 , How many oxygen atoms are present in 5 moles of diphospurus pentoxide ?

Is it 25 mol Oxygen ?

Answer 1

yes

Answer 2

if they're asking for atoms, though, you have to multiply by avogadro's constant.

Answer 3

so if atomms were asked should be 5 x 16 ?

Answer 4

if it's atoms (of oxygen only) multiply the number of moles (in this case 25) by avogadros number (6.022x10^23)

Answer 5

or is this what you call molecular formula?

Answer 6

I see :)

Answer 7

thanks :)

Answer 8

yeah, \(P_2O_5\) is the molecular formula.

no problem dude
