What is the mass of
What is the mass of
(a) 6.02×1023 atoms of oxygen.
Ans: – The masses of oxygen are 16gm as 1 mole oxygen has this no of atoms
(b) 6.02×1023 molecules of P4.
Ans: – 31g phosphorus has this no of molecules so the total weight of P4 is 31×4=124.
(c) 3.01×1023 molecules of O2.
Ans: – 1 mole O2 has 16g of oxygen so this no of molecules has 0.5 mole or 8gm of molecules.
