what do you mean? simple math

if you have N mol of a molecular in 1mole of solution solution, how many moles are there in .5M, how about .05M?
Summersnow8
  • Summersnow8
would it be, if they have a 2:2 relationship.... they would both be the same at 0.05M ?

I guess the answer is the 1st one, but i don't get why
caozeyuan
  • caozeyuan
well, I am going to say it explicitly now. 0.05*2=0.1, get it?
Summersnow8
  • Summersnow8
so because each has 2 moles.... you multiply the moles by the 0.05 M, each one is .1 that means the answer is the 3rd choice
