Question:

Given a group of n people sitting around a circular table, how many possible ways exist of different seatings of people

Rahul N.
Answer:

(n-1)!. As we have to consider that in case of circular permutations, we can't really define the beginning or the end of the string/order of people. Hence 1234 is same as 2341 or 3412. However 1234 is not same as 2314 as now even changing starting position does give us same order. This multiplicity results in a decrease of the order of permutation that is for a group of n things, total permutations will be (n-1)!

Question:

What is the difference between Molarity and Normality of a solution?

Rahul N.
Answer:

In simple terms, molarity refers to as the number of moles of the solute present in the solution. However for normality, instead of moles, it is the number of equivalents. Normality = n-factor * Molarity. n-factor depends upon specific activity of the compound in the reaction. As in generally for acids, n-factor denotes how much H+ they can donate per molecule.
