Assignment 2A

I faced some difficulties doing my assignment 2A...I did try my best
to do the questions and to clarify my doubts with Ms Jee..I felt questions
2C and 3 were the challenging ones for me..After using the ratio method,i
understand the concept better..I also noticed tat forgetting to write the
units and not rounding off to three significant figures will result to deduction
of marks..

Learnt something new:)

I learnt something new today..Mole of a substance is the same as Amount of
a substance..The meaning remains the same..But i kept forgetting to write it
as amount of mole..Besides these, i also learnt that relative molecular mass
equals to sum of the relative atomic mass..The difference is tat relative
molecular mass is the sum of the relative atomic masses of all atoms whereas
relative atomic mass is the mass of one atom of an element..After all the
explaination, my class was asked to do tutorial 2A..

The First Chapter

Finally i managed to post my thoughts...The first chemistry topic i learned
was Atoms, Molecules and Stoichimetry..While revising on the chapter,i was
not sure what is the difference between relative atomic mass and relative
molecular mass..Miss Jee always advise to ask questions to ourself in order
to clarify our doubts..it really worked..The difference is that atomic mass is the
mass of one atm of element whereas molecular mass is the sum of relative
atomic mass..However relative molecular mass = sum of the relative atomic
mass..it is abit confusing..:(
