Question

How to find kc from log kc?

Answer 1

Answer:

logKc = 15.6

=> KC = antilog 15.6

Now think log of which number can result in 15.6? There is 15 so it must be log10^15. (Log10^15 = 15) for 15.6 you have to add 0.6 in 15. Now think what is the number of whose log value is 0.6?

Log3= 0.47 which is 0.5 approx

Log5= 0.69 which is 0.7 approx. So 0.6 must be about log4. Taking approximations into consideration, it should be a lil less than log4 like log3.9.

The net answer comes as 3.9×10^15 !
