The number of moles you got is right. Though they asked that thses moles are in 0.2 g of oil so in 100 g of oil we had to multiply moles by 500 and the moles came were 0.45 something 0.45 x 2(126.9)= 114.8 g 80 is wrong
Hey I have 3 questions about section A What was the 1st answer? I put C (3) What was the conc of na2s04? I guessed and put 0.5 What was organic molecule using wave number And? I out the aldehyde one Ty guys
How did people explain what was going in step 1 and 2 of the thermal decomposition of Mg(NO3)2
Step 1: I assumed that some of the Mg(OH)2 had precipitated out of the solution and that upon heating its solubility increases and so dissolves back into it.
Step 2: Water was evaporating and CaO was being formed via thermal decomposition

Yeah first one I put C too, I put 0.33 for the concentration. And I take it you mean the IR spectra, where I also put the aldehyde.
