Acertain compound has an empirical formula of nh2o. its molar mass is between 55 and 65 g/mol. its molecular formula is

To determine the molecular formula, we make use of the empirical formula and the range of the molar mass of the compound. The empirical formula formula is a formula that gives the proportions of the elements present in a certain compound. It gives the lowest possible ratio of the elements. Determining the molecular formula, we multiply a factor to the empirical formula and calculate correspondingly the molar mass  of the compound. We do as follows:

                     molar mass
NH2O              32.02 g/mol
N2H4O2         64.04 g / mol

It is said that the range of the molar mass is 55 to 65 g/mol. So, probably, the molecular formula would be N2H4O2.

False because saturated fatty acids contain only single bond
