mMoles in Calculationsby chemistryprofessorpc630 views
Wonderful video rated you 5/5. I have a math inability so I always respected chemists perhaps more than any degree in college. I can't tell you how unbelievably hard it was to get a bs being math challenged constantly~so your videos are now my favorite all over again!

i have another question
calculate the % of calcium in 26 g of oxalate.

Perhaps your problem with this question is the way in which it is written. You are asked the % calcium in oxalate, but what is is really asking is the percent of calcium in calcium oxalate, CaC2O4.
Now, try it.
