What is the mass of one molecule?

Question

For the compound XeOF4

Answer 1

Add up the molar masses of each atom Xenon Oxotetrafluoride to get the mass of this compound for one mole of it containing 6.023 x 10^23 atoms. You have Xe (131.293 g/mol) + O (16.0 g/mol) + F (4 x 19.0 g/mol) =

about 223. g/mol

Answer 2

Xe-131.3

O-16

F-19

XeOF4=131.3+16+(4*19)=223.3g

6.022*10^23 molecules(1 mole) have the mass=223.3g

one molecule = 223.3/(6.022*10^23)g

do the rest yourself...

Answer 3

You can do it yourself.   Add the atomic mass of Xe, O, and 4 F atoms.
