The question makes it seem like 2.1 g of ice melted..
Also, qn 6b), they've inverted the equation to find the refractive index.. the 30 degrees angle is like the incident angle, however they've assumed it's the refractive angle. I'm not sure why, but is it because, if the angle we're trying to calculate, were to emerge into the glass, that's the angle it would form?
Help please :(

Hey, so i see someone answered ur second question but for the first one..I got a little mixed up with that as well.
What they are asking is for the amount of water that was melted.. AND that is in the beaker. So therefore u gotta do..18.4- 2.1, which then equals 14.2.
I dont know if that was understandable, i mean im remembering the question of the top of my head.
By the way, was it me, or was the paper a little hard. What do u think Hope??? Noone will answer this question -.-
AND ALSO I THINK THE MARK SCHEME WAS WRONG!!!!!! I thought that too, because for sure it is Sini/sinr
