I start with 3 mL of [Ru(bpy)3](PF6)2 solution. Every time Add 100 uL volume of DPA solution with 0.05M. Do it five times, the total amount of DPA is 500ul

V concentration of DPA
100ul
200ul
300ul

400ul

500ul

I am so confused about how to calculate the concentration of DPA in each adding

What is the excel function/equation to add every ten numbers. I have a list of 100 numbers or so in a row. I want to add the first ten numbers and put the value in the row below the list. So add numbers 1 to 10, 2 to 11, 3 to 12, and so on. There has to be an easier way to do this than manually right?
