The molecular formula mass of this compound is 240 amu . what are the subscripts in the actual molecular formula? enter the subscripts for c, h, and o, respectively, separated by commas (e. g., 5,6,7)

The empirical formula : CH₂O  

The molecular formula : C₈H₁₆O₈

the subscripts for C, H, and O : 8,16,8  

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

(empirical formula) n = molecular formula  

The principle of determining empirical formula and molecular formula

Percentage of elements A and B in AxBy compounds:  

% A in AₓBy = (x x Ar A / Mr AₓBy) x% AₓBy  

% B in AₓBy = (y x Ar B / Mr AₓBy) x% AₓBy  

It is known about the% mass of each element  

The complete question must be :

A Compound Is 40.0 % C, 6.70% H, And 53.3% O By Mass. Assume That We Have A 100g Sample Of This Compound. The Molecular Formula Mass Of This Compound Is 240 Amu. what are the subscripts in the actual molecular formula? enter the subscripts for c, h, and o, respectively, separated by commas (e.g., 5,6,7)

To find the empirical formula, we look for its mole ratio (% mass/ its relative atomic mass)  

C = 40 / 12 = 3.3

H = 6.70/ 1 = 6.70

O = 53.3 / 16 = 3.3

To simplify the comparison as an integer, we divide by the mole ratio of the smallest element  

C = 3.3/3.3= 1

H = 6.7 /3.3 = 2

O = 3.3/3.3 = 1  

So the empirical formula:  

CH₂O  

We look for the molecular formula to get the number of atoms making up the compound  

(CH₂O) n = molecular formula  

(1.12 + 2.1 + 16) n = 240

(30) n = 240

n = 8

So molecular formula = C₈H₁₆O₈

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
