Theoretical mass :/
Hey tsr
I know how to get the mass of a substance (amount x molar mass) but I can't do that here as there's no amount(?)
So far I've just got 120.5 (the molar mass)
Any help will be appreciated
(question 3. b)

Actually I think I've got it
0.0285 X 120.5 ?

Look at the mole ratios in the equation

A 1:1 ratio?

Correct and you worked out moles for something for part a) right?

Yup I did 2.45/86 = 0.0285

Ill assume your maths is right (I'm at work), now you can use that amount of moles for part b) to work out mass
