Given two positive numbers calculate their weighted average(Note: This is not actually a homework question, but silly me have doubts, so I put it in this category)
Homework Equations
Two given positive numbers a,b. No separate weights are available to weigh each...
Thanks
Many thanks for this great tutorial. I would also suggest that you discuss some tricky questions on acids/bases and pH like:
1.How a solution of Ammonium Acetate can act as a buffer
2.What is the pH of 10^-8 m HCL solotion?
3. Can pH be lesser than zero or greater than 14?
Thanks...
