Concept explainers
Interpretation : The empirical and molecular formula of the compound should be calculated.
Concept Introduction : Any compound can easily represent with the help of molecular formula. Another type of formula is empirical formula which represents the lowest whole number ratio of atoms in a compound. It does not represent the actual number of atoms in the molecule. The relation between molecular formula and empirical formula can be written as;
Molecular formula = small integer x empirical formula
The following steps should be followed to get the molecular formula:
1. Calculate the number of moles for each element.
2. Divide by smallest number of moles.
3. Write the empirical formula with the help of whole number of step-2.
4. Calculate the mass of empirical formula with the help of
5. Calculate the integer value and find the molecular formula.

When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] . When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color isarrow_forward
