Is molecular formula and chemical formula the same?
A molecular formula is not a chemical name, and it contains no words. Although a molecular formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Molecular formulas are more limiting than chemical names and structural formulas.
What is molecular and chemical formula?
: a chemical formula that gives the total number of atoms of each element in each molecule of a substance — compare structural formula.
What is the molecular formula examples?

What is the molecular formula of water?
What is chemical formula of ethanol?
The molecular formula of ethanol is C2H6O, indicating that ethanol contains two carbons and an oxygen. However, the structural formula of ethanol, C2H5OH, provides a little more detail, and indicates that there is an hydroxyl group (-OH) at the end of the 2-carbon chain (Figure 1.1).
What is the molecular formula of washing soda?
Washing soda is a chemical compound with the formula Na2CO3, also known as sodium carbonate, and it’s a salt of carbonic acid.
Which formula is an empirical formula?
In chemistry, the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. A simple example of this concept is that the empirical formula of sulfur monoxide, or SO, would simply be SO, as is the empirical formula of disulfur dioxide, S2O2.
What is aldehyde formula?
Aldehyde is a chemical compound with a functional group -CHO. The general formula of alkene is CnH2n+1 so the general formula for aldehyde will be CnH2n+1CHO or CnH2nO.
What is Ketone formula?
The general formula of ketones is, CnH2nO. The simplest ketone is of 3 carbon atoms, so its formula will be, C3H6O, called as propanone, it can also be written as, CH3O||CCH3, the carbon of the ketone is counted with the carbon of the hydrocarbon. Hence, the general formula for ketones is CnH2nO.
What is the chemical name for gypsum?
