What is molecular formula of C4H9?

Molecular FormulaC4H9. Average mass57.114 Da.

What is the correct formula for C4H9?

(4×12.011+9×1.00794)g⋅mol−1×n=114.26⋅g⋅mol−1 . Here I used the atomic masses of carbon and hydrogen. It is pretty clear that the mulitple, n , =2 . So molecular formula =[EF]n=2×(C4H9)=C8H18 .

Is caffeine acidic or basic?

On the pH scale, the acid content in coffee ranges from about 4.85 to 5.10, making it an acid, not a base. And as delicious as it may be, because coffee is acidic, it can be difficult for people with certain health conditions to enjoy. For most people, drinking a cup of coffee with a pH level of 5.0 is perfectly fine.

What is an example of molecular formula?

Molecular formulas describe the exact number and type of atoms in a single molecule of a compound. For example, the molecular formula of sodium fluoride is NaF. A molecular formula is not a chemical name, and it contains no words.

How do you use the molecular formula?

Divide the molar mass of the compound by the empirical formula molar mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.

Is alcohol acidic or basic?

By the Arrhenius Definition of an acid and base, alcohol is neither acidic nor basic when dissolved in water, as it neither produces H+ nor OH− In the solution. Alcohol with a pKa of around 16−19 , they are in general, slightly weaker acids than water.
