1.	) HBrRearrange the following I to IV) in the orderof increasing masses and choose the correctanswer from (a) (b) (c) and (d). Atomic masses:N=14, O = 16, Cu = 63I. 1 molecule of oxygen II. 1 atom of nitrogen111.1 Ă 1010 g molecular weight of oxygenIV. 1 x 10-18 g atomic weight of copper(a) I <I< III < IVh) IV I< II<I
Answer» 1 molecule of oxygen weighs = 32gm and 1 atom of nitrogen weighs = 14gm here II<I so, 1 will have the largest mass , then 2 then 3 and 4 only option following is .. B. correct answer is A .....

Answer»

1 molecule of oxygen weighs = 32gm and 1 atom of nitrogen weighs = 14gm

here II<I

so, 1 will have the largest mass , then 2 then 3 and 4

only option following is .. B.

correct answer is A .....
