What is the empirical formula of a compound with the molecular formula C6H12O6?
The empirical formula of this compound is CH2O.
What is the molecular formula of a compound that has a molecular mass of 46 and an empirical formula of No2?
The molecular formula is the same as the empirical formula, NO2. The compound NO2 has a molar mass of 46g/mol, so the empirical and molecular formulas are the same.
Can the empirical formula of a compound be triple its molecular formula?
No: The molecular formula is never smaller than the empirical formula.
What is the empirical formula for compound whose molecular formula is P4O10?
The empirical formula for a compound whose molecular formula is P4O10 is P2O5 = phosphor pentoxide.
What is the molecular formula of a compound that has a molecular mass of 92 and an empirical formula of No2?
The formula of NO2 has a molecular weight of 46 g/mol. Your compound has a molecular weight of 92 g/mol. As you can see the molecular weight of the compound is twice that of the empirical formula. Therefore the molecular formula of your compound is:2 *(NO2) ---> N2O4
Can an empirical formula be a molecular formula?
Yes, the empirical formula is the most basic ratio of the elements in a compound, while the molecular formula is the ratio in a compound. For instance C5H10O could be both the empirical and the molecular formula or the molecular formula could be C10H20O2 the molecular formula depends on the molar mass.
How are the empirical and molecular formulas for a compound related?
A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.
What is the empirical formula for a compound whose molecular formula is C2Cl6?
Empirical Formula: CCl3
Can empirical formula be the same as the molecular formula?
An empirical formula may or may not be the same as a molecular formula. The empirical formula of a compound shows the smallest whole-number ratio of the atoms compound. The molecular formula tells the actual number of each kind of atom present in a molecule of the compound.
What is an empirical formula?
The chemical formula in which the subscripts are given in the smallest ratio.
How to calculate Molecular formula from empirical formula?
If you know the molar mass of the compound, you have to calculate the mass of the empirical formula and divide the molar mass of the compound by the mass of the empirical formula in order to find the ratio between the molecular formula and the empirical formula. Then multiply all the atoms by this ratio to find the molecular formula!
What is the molecular formula of a compound with an empirical formula of CH?
The simplest compound is acetylene, C2H2.
What is the molecular formula of a compound given that molar mass of the compound is 30.04 gram and the empirical formula is NH?
The molecular formula of this compound is N2H2. This is obvious because the empirical formula of a compound is the lowest positive integer ratio of atoms present.
How do you determine a empirical formula?
Empirical formulas are the result of chemical analysis of a compound.
What is the empirical formula of a compound with the molecular formula C 12 H 8?
Empirical formula: C3H2
Determine the molecular formula of a compound if its empirical formula is C2H6O and its molar mass is 138g?
Because an empirical formula is the simplest form of a compound, we know that the molecular formula contains more atoms than it does. Since we are given the molar mass, we can use this formula. x ( MM of empirical formula ) = MM of molecular formula MM of empirical formula = 12(2) + 1(6) + 16 = 46 MM of molecular formula = 138 46x = 138 x= 138 / 46 x=3 Therefore, the molecular formula is 3(C2H6O) that is C6H18O3
What do empirical formulas tell you?
The empirical formula tells you the simplest formula for the compound. The molecular formula will be some multiple of the empirical formula, or it can be identical to the empirical formula.
What is the molecular formula of a compound having the empirical formula of CH2O and a molecular mass of 120amu?
The molecular mass of a compound with the formula CH2O is approx. 30, not 120.
What formula represents a molecular compound?
This is the chemical formula (empirical formula) or the formula unit of this compound.
How are empirical and molecular formulas for a compound created?
An empirical formula is elaborated after the chemical analysis of a compound; for a structural formula more in depth studies are necessary.
