can someone run through the yield question for me?
totally suck at yield
>.<

say that you calculate that you should get 2g of a molecule, but you only get 1g after your reaction.

you would do amount (in g) obtained *100/ amount calculated possible.

so in this case 1*100/2 = 50%

It's the mass you get expressed as a percentage of the mass you expected.

I think of it as how "happy I am" percentage.

Like I expect to get 100 marks out of 100 for a test.

But i only get 67 marks.

Iam so i am 67 parts out of 100 happy so 67/100 *100 = 67% yeild of happiness  :smitten:

lolllllll, great analogy

i just did this, and yes i agree with you martoman, it was ridiculously easy-
exceptt the mark i lost was something i actually didn't know since i keep avoiding going over biofuels - i didn't know that the fermentation reaction of glucose had a 'general name' of oxidation reaction, so unless vcaa is nicer, i lost a mark for saying fermentation;p
it's fine though since the exam is out of 86

[Martoman]

 your happiness yield was 85 / 86 * 100 ?

your happiness yield was 85 / 86 * 100 ?

haha pretty much, and i was expected the theoretical yield- but like aspirin that never happens><
