n then the total A was equal for s3 n s4

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?

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

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
