Question

No of moles in 500cc of water

Answer 1

Answer:

500cc=500ml=500g

So,

the number of moles of water =500 / atomic weight =500/18=27.78 moles

Thus, the number of molecules would be = No. of moles × Avogadro's No.

or, the total no. of molecules =27.78×6.023×10

23

=1.67×10

25

and each water molecules has 10 protons in it.

Thus, total no. of protons in 500cc of water would be = total number of molecules ×10=1.67×10

26

protons.

the total protonic charge = number of protons × protonic charge

Q=ne

=1.67×10

26

×1.6×10

−19
