What was to be written in that four mark part, the observation in the last question? I wrote it is an alkene and a ketone is formed but it was of four marks so what further was to be written. Please answer this.

How was x 2? It was 30! Why did everyone use .05 moles of the compound? We had to divide it by 5 necause we only used 1 relative mole of the compound instead of the 5 that was given in the equation. So 0.05/5= .01....6.3/0.01= 630...630-90/18=30
