What will be the weight of CO having the same number of oxygen atoms at present in 22 g of `CO_(2)`?

Options

A. 28g
B. 22g
C. 44g
D. 72g

Explanation

No. of O atoms in `CO_2=2`
Molar mass of `CO_2=44g`
44g `-= "1 mol " rArr` 22g=0.5 mol
1 mol of `CO_2 " contains " 2xx6.023xx10^23` O atoms
0.5 mole of `CO_2=6.023xx10^23` O atoms
mole of CO `=6.023xx10^23` O atoms
Mass of 1 mole of CO = 12 + 16 = 28g
