Answer to Question #28128 in Inorganic Chemistry for abhishek
a sample of phosphorous has 0.5 moles of p4 atoms.calculate:-
(a)how many p atoms are there?
(b)how many moles of p atoms are there?
a) Each mole contains 6.022 x 10 SQR (23) of molecules. Each P4 molecule contains 4 atoms.
0.5 moles of p4 contain: 0.5 x 6.022 x 10 SQR (23) x 4 = 12.044 x 10 SQR (23) p atoms.
b) As we can see from formula P4, each mole of it contains 4 moles of atoms P.
So, 0.5 moles of P4 contain: 0.5 x 4 = 2 moles of P atoms.
