There isn't enough information.

C3NH8

C3NH3

To determine the molecular formula of compound A, we need some additional information. The relative mass, also known as the molar mass, gives us the mass of one mole of the compound. However, it does not provide specific information about the types and numbers of atoms present in the compound.

In order to find the molecular formula, we need the empirical formula and the molar mass. The empirical formula represents the simplest whole-number ratio of atoms in a compound. To determine the empirical formula, we usually need the mass of each element present in the compound or the percentage composition of each element.

If you have the empirical formula of compound A or its percentage composition, please provide that information so that we can help determine the molecular formula.
