Students have asked these similar questions
you are to determine the molecular formula for a molecular compound consisting of only carbon & hydrogen. The molar mass of this compound is 42.08 g/mol.
Part D:
The empirical formula has a molar mass of 14.026 g/mol (this is called the empirical molar mass). Divide the molar mass for the total compound given above by the empirical formula molar mass.
This will give you a number for multiplying the carbon atoms and hydrogen atoms in the empirical formula.
What is the multiplication value?
An unknown compound comprised of osmium and chlorine is 40.11%
osmium by mass.
a) If you assume 100.0 g of the compound, what is the mass in grams of
osmium that are present in the compound?
b) How many moles of osmium are present in 100.0 g of the compound?
c) If you assume 100.0 g of the compound, what is the mass in grams of
chlorine that are present in the compound?
!!!
d) How many moles of chlorine are present in 100.0 g of the compound?
e) Determine the empirical formula of the unknown compound.
f) What is the IUPAC name of the compound?
What does the word “empirical” in empirical formula mean? If we know the empirical formula of a compound,what additional information do we need in order to determine its molecular formula?
