A) 300
B) 440
C) 350
D) 500
Correct Answer: D
Solution :
The compound must contain at least one oxygen atom So, a minimum of 1 g atom of oxygen will be present in 1 g molecule, i.e., 1 mole of the compound. If Mis the mol. wt. of the compound, then since 16 is the atomic mass of oxygen so minimum of 16 g of oxygen will be present in M g of the compound Thus, \[%\] of oxygen \[=\,\,\frac{16}{M}\times 100\] or \[3.2\,\,=\,\,\frac{16\times 100}{M}\] or \[\operatorname{M}=500\]You need to login to perform this action.
