RafaTo find the formula mass of a compound, you calculate the sum of the atomic masses of all the elements in the compound according to their molecular formula. This can be done by looking up the atomic masses of each element on the Periodic Table and multiplying them by the number of atoms present in the formula.

How do you determine empirical formula with compound elements?
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.
What is the formula for density of a planet?
The formula for density of a planet is mass divided by volume. It is given by the equation: density = mass / volume.
What is the formula to find mass with only the density and volume?
The formula to find mass with density (ρ) and volume (V) is: mass = density × volume
Is the following nuclear reaction balanced?
A nuclear equation is balanced when the sum of atomic numbers and mass numbers on each side of the equation is the same.
Vitamin c has an emperical formula of c3h4o3 and a molecular mass of 176what is the molecular formula of vitamin c?
To find the molecular formula from the empirical formula, we need to know the molar mass of the empirical formula. In this case, the empirical formula's molar mass is 88. To find the molecular formula, we divide the given molecular mass (176) by the empirical formula's molar mass (88) to get 2. This means the molecular formula of Vitamin C is twice the empirical formula, so the molecular formula is C6H8O6.
