1.	A given compound always contatins exactly the same proportion of elements by weight’. Calculate the number of molecules in each of the following: 1g N_2(Given that N_A is 6.02xx10^23, molecular mass of N_2 is 28 and CO_2 is 44).
Answer» SOLUTION :NUMBER of MOLECULES PRESENT in `1gN_2="MASS"/"Grammolecular mass"xxN_4=1/28xx6.02xx10^23=2.15xx10^22`
