Question #28128

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)how many p atoms are there?

(b)how many moles of p atoms are there?

Expert's answer

a) Each mole contains 6.022 x 10 SQR (23) of molecules. Each P

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 P

So, 0.5 moles of P

_{4}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 P

_{4}, each mole of it contains 4 moles of atoms P.So, 0.5 moles of P

_{4}contain: 0.5 x 4 = 2 moles of P atoms.Need a fast expert's response?
