Means if you get around 30 in P3 out of 40,you get 22.5/30.Right?

wait so like if I end up getting an A like past the gt in paper 3, does that mean that when they do it out of 30,it'll still remain inside the gt for an A?

then the overall gt will also be tougher to get to cuz no matter how low the gt for p3 is the total gt always remains the same for s3 n s4

p22

WHHAAAATTTT 6 SF?!?!? Which question is this? the only one i remember was in the first question and they said 4 sf.....

 

[Roe Mir]

Why lid is placed while cooling? And improvement?
I wrote to prevent residue loss and improvement use larger mass so that uncertainty will be reduced...
And what was your percentage purity ?mine was 99.5%

Mines was 90 point something %. As long as its in 90's i think its alright

 

[Zaki ali asghar]

in the preceding part i calculated mass using an incorrect method which came as 1.0g and my measured mass was 1.9g in first part so i calculated % diff as 1/1.9*100=52.6% will i be getting ecf as i used the same % in the second q as well so worried

 

[ErosKuikel]

Whats the ans to qn 2c(i),, suggesting improvement of the exeriment using the same masses???
I'm talking about p31...
