Answer #1

Molecular formula of the given compound is C4H8O2 .

The molecule has four carbon atoms, eight hydrogens and two oxygen atoms.

2) Benzoic acid has molecular formula of C7H6O2

Therefore molecular weight is = (12*7)+(1*6)+(16*2) = (84+6+32) = 122

3) Sodium carbonate have a molecular formula of Na2CO3 and is a base which is frequently used to neutralizes the solution

Option D is correct
