Help with mol and volume calculations - Cram's rule

Message
[QUOTE="Borek, post: 6400007, member: 23711"] No. Sanity check: you have 60.8 g of Mg, molar mass of magnesium is 24.3 g/mol, is it possible to have 0.4 moles of Mg if you have several times more than the molar mass? It is a bit like saying "I have 60 marbles, box holds 24, so it will be filled in 40%". That's what you will have to do, but you are doing some strange things - what does "5 equivalents" mean and where does this number come from? Can't be, you are told there were 268 g of the aldehyde used. On the second thought: that's probably mass of the aldehyde you are expected to do calculations for, using the data from the Cram's paper (as if you were planning to do the reaction using 0.54 g of the aldehyde instead of 268 g used by Cram).
