The empirical formula of a compound is determined to be CH2O, and its molecular mass is found to be 90.087 g/mol. Determine the
IrinaVladis [17]
To find the molecular formula of the compound, we get the molar mass of empirical formula CH2o which is 30 g/mol. We divided  the molecular mass of 90.087 g/mol by 30, we get 3. Hence, we multiply each element by 3, getting the molecular formula of C3H6O3.

What is the state of matter for 2NH3, 2NaCl and 2KNO3+PBI2.
Aloiza [94]

Answer:

2NH3 - Gas Phase

2 NaCl - Solid Phase

2KNO3+PBI2 - Aqueous Phase

Explanation:

2NH3 is ammonia gas which is colorless and has a bad pungent smell.  

NaCl is salt. It has crystalline structure and can exhibit both aqueous or a liquid phase. Since there is no H2O molecule in the formula of NaCl, hence it is not aqueous. It is not liquid as well because liquid NaCl is represented as NaCl (l) while aqueous NaCl is represented as NaCl (aq).

The reaction 2KNO3+PBI2 will take place in aqueous phase and hence these two exists in aqueous phase
