Okay, I am trying my best to achieve an A or A* grade in ocr chemistry gcse, and I think I can do it, if I learn how to do the hard equations in C5. A question I just attempted (and epically failed at..) was this one:
KOH + HNO3 -> KNO3 + H2O
The concentration of potassiumhydroxide solution is 0.100mol/dm3
Calculate thenumber of moles in 25.0com3 of potassium hydroxide solution
Is this right?
