Sachin and Sanjana are calculating 23 % of 800.
Now, calculate 52 % of 700 using both the ways described above. Which way do you find easier?
First way 52% of 700=(1% of 700)×52=(1100×700)×52=(0.01×700)×52=7×52=364 Second way 52% of 700=52100×700=0.52×700=364 So, second way, we have to find easier.
Is there any easier way used to split the middle term? Is there any easier way for the calculation?
I have two questions which are almost similar but answers are given in two different ways..
questions are:Q1)Assuming complete dissociation calculate pH for 3×10^-3M HCl?
Q2)Calculate pH of a 1×10^-8M of HCl?
I know the answers of both questions but they are done in different ways..So is there any difference?
