its the mass thats given over the mass you had at the beginning... i need an example to explain it better..Can someone explain percentage error calculation? :/

Thats the percentage yield. Im talkin about the percentage error or percentage uncertainty...its the mass thats given over the mass you had at the beginning... i need an example to explain it better..
Can someone explain percentage error calculation? :/
Yeah i know that. But sometimes they multiply the error by another number. How do u find that number?= Error/actual measurement * 100
Generally asked for apparatuses like cylinders or temperature of +-0.05?Thats the percentage yield. Im talkin about the percentage error or percentage uncertainty...
Yeah. Thats correct.Generally asked for apparatuses like cylinders or temperature of +-0.05?
Im going through it now .. It is an endothermic reaction.ah..the mark scheme.. i checked it out too. but i didn't know how..??
yeh so basically its the error/the actual thing *100... smetimes for the mass you need to check the equation and check the mole ratio.. for ex:.mass used for KHCO3= 2.00g and in the equation its 2KHCO3 error of mass =+-0.01g... therefore 2*0.01/2.00 *100Yeah. Thats correct.
you're dehydrating the crystals..Im going through it now .. It is an endothermic reaction.
Youh got it eh I didn but..
Thanks alot!yeh so basically its the error/the actual thing *100... smetimes for the mass you need to check the equation and check the mole ratio.. for ex:.mass used for KHCO3= 2.00g and in the equation its 2KHCO3 error of mass =+-0.01g... therefore 2*0.01/2.00 *100
no problem. Glad i helpedThanks alot!
Can someone help me with the Iodine-thiosulfate titrations? like explain it to me. The calculations and steps.
Its there on the June 2010 Unit 3 paper. Question 3. Its about that titration. In my text book they have that topic but i don't completely understand the calculations. That is why i would like someone to explain it to me.where did you find that?

;D.. Juz Came Bak Aftr Exam Chem 3b:/ Have You Done Well ^.^you're dehydrating the crystals..
