Interpretation:
Whether a molecular formula of a compound can be 2.5 times its empirical formula or not needs to be explained.
Concept introduction:
The empirical formula tells about the simplest ratio of atoms of present in the molecule. It does not give the actual number of atoms present in the molecule. The molecular formula shows the actual number of atoms present in the molecule.
Answer to Problem 67SSC
No, molecular formula of a compound cannot be 2.5 times its empirical formula.
Explanation of Solution
The simplest ratio of atoms present in a compound can be represented by its empirical formula. On the other hand, the exact ratio shows the molecular formula.
The ratio of molecular formula to empirical formula always gives a natural number
For examples, molecular formula of hydrogen peroxide is H2O2 but its empirical formula is HO. Here, the molecular formula is 2 times the empirical; formula.
Hence the experimental claim of the student is false.
This statement made by student is wrong.

- need help not sure what am doing wrong step by step please answer is 971A During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration. What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).arrow_forwardInfluence of salt concentrations on electrostatic interactions 2 Answer is 2.17A why not sure step by step please What is the Debye length in a concentrated salt solution with an ionic strength of 2.00 mol/l?
