1.	Rearragne the following (I to IV) in the order of increasing masses and choose the correct answer (Atomic masses O=16, Cu=63 and N=4) I. 1 Molecule of oxygen II. 1 atom of nitrogen IIIgt 1xx 10^(-10)g atomic weight of copper
Answer» II lt I lt III lt IV IV lt III lt II lt I II lt III lt I lt IV III lt IV lt I lt II Solution :a) I. 1 molecule of `O_(2)` = (32)/(6.022 xx 10^(23)` = 5.3 xx 10^(-23)`G (ii) 1. atom of N= (14)/(6.022 xx 10^(23)`g = `2.3 xx 10^(-23)`g IIIgt `10^(-19)` g MOLECULAR weight of oxygen `= (10^(-10) xx 32 = 3.2 xx 10^(-9)`g IV. `10^(-10)`gatomic weight of copper `= 10^(-10) xx 63 =6.3 xx 10^(-9)`g `therefore` ORDER of increasing mass is II lt I lt III lt IV
