What information is given by a molecular formula?
the empirical formula and the molar mass
What is its molecular formula if the molar mass of the compound is 199.55 grams per mole?
Cannot answer this question without knowing the EMPIRICAL formula.
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
What steps are used to convert an empirical formula into a molecular formula?
By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.
What is the properly written empirical formula of a compound of molecular formula C6H12 with a molar mass equal to 84.16 gram per mol?
The information about the actual molar mass is superfluous. Given any molecular formula, the corresponding empirical may be obtained by dividing all the subscripts in the molecular by the largest integer that yield an integer quotient for each subscript. In the given formula, the empirical formula is CH2.
What is the molecular formula of a compound with the empirical formula C13H19O2 and molar mass of 414.64g?
C26h38o4
What is the molecular formula of a compound with the empirical formula NH2Cl and molar mass of 51.5g mol?
Nh2cl
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.
What information is given by a molecular formula?
the empirical formula and the molar mass
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.
What is the molecular formula of a compound whose empirical formula is CH3 and whose molar mass is 30 g?
C2h6
What is the molecular formula of a compound that has an empirical formula of c2oh4 and a molar mass of 88 grams per mole?
C4O2H8
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 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.
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 is the molecular formula of compound CH2 with a molar mass of 42.0?
The empirical formula CH2 has a formula mass of 14, and 42.0/14 = 3. Therefore, the molecular formula is C3H6.
What is its molecular formula if the molar mass of the compound is 199.55 grams per mole?
Cannot answer this question without knowing the EMPIRICAL formula.
