Find the equivalent weight of Al2(SO4)3

Answers

Answered by varaddaithankar

Eq weight = Molecular wt/n

here n=3×2 .....for 2 Al

Molecular wt is 342/6

Phosey: yep

Phosey: if ratio of nitrogen to oxygen present in a compound by mass is 7:8 then the ratio of number of atoms of nitrogen to oxygen is

Phosey: what should be the answer of this question.......

Phosey: I am not getting the write answer...

varaddaithankar: mass ratio is 7:8 so let us say nitrogen mass is 7gm and oxygen 8gm

varaddaithankar: so moles of nitrogen are 7/28=1/4 moles.....since nitrogen is present in N2 state

varaddaithankar: moles of O2 are 8/32=1/4

varaddaithankar: so no. of atoms of N2 are moles*2*Avagadros no........2 for 2 molecules of N and similarily for O2

varaddaithankar: this ratio would come 1:1 ....which is the answer

Phosey: thanks
