Question

Study the following table

	Compound (mol. mass)	Mass of the compound (in gram) taken
$I .$	$C O_{2} (44)$	4.4
$I I .$	$N O_{2} (46)$	2.3
$I I I .$	$H_{2} O_{2} (34)$	6.8
$I V .$	$S O_{2} (64)$	1.6

Which two compounds have least mass of oxygen?

TestHub · Accepted Answer

Mass of oxygen present = w t . o f C o m p o u n d M o l . w t . o f c o m p o u n d × 32 I. Mass of oxygen present = 4.4 44 × 32 = 3.2 g II. Mass of oxygen present = 2.3 46 × 32 = 1.6 g III. Mass of oxygen present = 6.8 34 × 32 = 6.4 g IV. Mass of oxygen present = 1.6 64 × 32 = 0.8 g So II and IV have least mass of oxygen.
