you have to test it first in an experiment, and then you have to write down your explanation of what you've just seen. In order to do that, you have to put 2 cups, label them with element B (E.B) and label the other cup with element A (E.A). put water in both and miz it with sugar, vinigar, salt, and cranberry juice. stir it and wa lah you just found the moluar mass. Moluar Mass=9+16.17/8*x-p*4^9

You'll need a lot more information about this substance than (only) this molar mass to find its formula, though it might help to confirm your findings.

A molecular formula comprises the constituent atoms of a molecule; to determine molecular mass, summate the atomic masses of the elements in their respective proportions.

How do you calculate Molecular formula from empirical formulaWhat could you do with that information to determine that the empirical and molecular formulas are related to one another by a factor of 6?

In order to find molecular formula from empirical formula, one needs to know the molar mass of the molecular formula. Then you simply divide the molar mass of the molecular formula by the molar mass of the empirical formula to find out how many empirical formulae are in the molecular formula. Then you multiply the subscripts in the empirical formula by that number.


How does on determine a molecular formula from the empirical formula?

molar mass over grams of elementThe above answer is somewhat correct. In order to find the molecular formula when given the empirical formula, you must first find the molar mass of the empirical formula.MOLAR MASS# atoms element A x Atomic Mass element A (Periodic Table) = mass A# atoms element B x atomic mass element B (periodic table) = mass B... etc.Add up all of the mass values found above and you have the molar mass.Then, after you have found the empirical formula's molar mass, you divide the molar mass of the molecular formula by the empirical formula's molar mass (solving for n).MOLECULAR FORMULA EQUATION: N (Empirical formula) (read as N times empirical formula) where:N = Molar mass substance---- Molar Mass emp. form.

How does one determine a molecular formula from the empirical form?

molar mass of unknown/molar mass of empirial = # of empirical units in the molecular formula. Example: empirical formula is CH2O with a molar mass of 30. If the molar mass of the unknown is 180, then 180/30 = 6 and molecular formula will be C6H12O6


What is relationship between the formula weight of a substance and its molar mass?

Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .


What is the molecular formula for the unknown C3H5O?

Empirical formula = C3H5O Molar mass of empirical formula = 3(12.01)+5(1.008)+1(16) = 57.07 Molar mass of molecular fomula = 114.15 n = Molar mass of molecular fomula/Molar mass of empirical formula = 114.15/57.07 n = 2 Molecular formula = n(empirical formula) Molecular formula = 2(C3H5O) = C6H10O2 Check: 6(12.01)+10(1.008)+2(16)= 114.14


How does one determine a molecule formula from the empirical formula?

The density or some other information must be given that allow you to find the molar mass. Calculate the empirical formula mass. Divide molar mass by empirical formula mass. This answer is multiplied by all subscripts of the empirical formula to get the molecular formula.

What is the molecular formula of the compound CH2 with molar mass = 42.0?

The molecular formula of a compound can not be determined solely based on its molar mass. In this case, without additional information, it is not possible to determine the molecular formula of the compound CH2.


What is the molecular formula of the molecule that has an empirical formula of CH2O and a molar mass of 120.1g?

The molecular mass of a compound with the formula CH2O is approx. 30, not 120.
