The molecular formula mass of this compound is 210 amu What are the subscripts in the actual molecular formula Enter the subscripts for C H and O?
Element Element's atomic mass
C : 12
H2 : 2(hydrogen's atomic mass is 1 but remember there are two)
O : 16
Add all the elements atomic mass and then divide the molecular mass by it. After that you only need to multiply all the subscripts of each element to find your answer.
12+2+16=30
240/30=8
8(CH2O) = C8H16O8
What else can I help you with?
The actual molar ratio of elements in a compound as expressed by the subscripts in a formula is expressed in what?
The actual molar ratio of elements in a compound as expressed by the subscripts in a formula is the formula unit. It represents the simplest whole-number ratio of atoms of each element in the compound.
What specifies the actual number of atoms of each element in one molecule of a compound?
This is specified by the subscripted number directly next right-down to the atom's symbol.Example: Sulfuric acid: H2SO4 has 2 atoms of Hydrogen, 1 atom of Sulfur and 4 atoms of Oxygen per molecule H2SO4
What could be a molecular formula for the empirical formula C2H2?
The molecular formula for the empirical formula C2H2 is also C2H2. The empirical formula gives the simplest whole number ratio of atoms present in a compound, whereas the molecular formula provides the actual number of atoms of each element in a molecule.
What is a molecular formula?
The molecular formula specifies the actual number of atoms of each element in a molecule.
Is the formula for methane both a molecular and an empirical formula?
Yes, the formula for methane (CH4) is both a molecular formula and an empirical formula. The molecular formula shows the actual number of each atom in a molecule (4 hydrogen atoms and 1 carbon atom), while the empirical formula gives the simplest whole-number ratio of atoms in a compound (CH4).
The actual molar ratio of elements in a compound as expressed by the subscripts in a formula is expressed in what?
The actual molar ratio of elements in a compound as expressed by the subscripts in a formula is the formula unit. It represents the simplest whole-number ratio of atoms of each element in the compound.
What is an emperical formula?
An empirical formula represents the simplest whole-number ratio of atoms in a compound. It does not provide information about the actual number of atoms present in a molecule. To determine the empirical formula, one must divide the subscripts of the compound's molecular formula by the greatest common divisor to obtain the simplest ratio.
What represents the actual number of atoms present in a compound?
The subscript (The small number at the bottom). Like SnO2. It shows that Sn is one atom together, and the O has 2.
How is a molecular formula writted?
Molecular formula is the Actual ratio of atoms of each element in the compound Ex. H20
What specifies the actual number of atoms of each element in one molecule of a compound?
This is specified by the subscripted number directly next right-down to the atom's symbol.Example: Sulfuric acid: H2SO4 has 2 atoms of Hydrogen, 1 atom of Sulfur and 4 atoms of Oxygen per molecule H2SO4
Can the empirical formula of a compound be triple its molecular formula?
No, the empirical formula represents the simplest whole-number ratio of atoms in a compound, while the molecular formula shows the actual number of each element present in a compound. Therefore, the empirical formula cannot be triple the molecular formula.
What specifies the actual number of atoms of each element inone molecule of a compound?
molecular formula
What type of formula is based on the actual number of atoms that comprise a molecule of that compound?
This is called an empirical formula.
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 difference between empirical and molecular formula?
An empirical formula is one that shows the lowest whole number ratio of the elements present. The molecular formula shows the composition of the molecules. An example is phosphorus pentoxide, P2O5 empirical formula, P4O10 molecular formula.
Is C4H10 an empirical formula or a molecular formula for butane?
C4H10 is the molecular formula for butane, as it represents the actual number of atoms of each element in a single molecule of the compound. The empirical formula for butane would be CH5, as it shows the simplest whole number ratio of atoms present in the compound.
What is the simplest part of a compound?
The simplest form for a compound, called the empirical formula, gives the simplest whole-number ratio of the elements in the compound, and may differ from the actual molecular formula. For example, the molecular formula for glucose is C6H12O6. The empirical formula would be CH2O, which can be found by dividing the molecular subscripts by 6.
