Analysis of an unknown sample indicated the sample contained 0.140 grams of N and 0.320 grams of O. The molar mass of the compound was determined to be 92.02 amu. What is the molecular formula of the compound?

let that person have a turn to speak : )

the dissolution of polymer can be thermodynamically described in 2 steps.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
