plz can anyone tell how to solve question no 22??
i.e what is the mass of decimole of electrons??
c.m.zeeshan said:
the mass of electorn is 54 mg here deci means 10 to raise powr -1 so by dividing 10 we got 0.54 mg ....... understand ???
ayesha said:
if we divide 54 by 10 then it will become 5.4 mg not 0.54 and the mass of one mole of ellectron is 0.54mg not 54 mg and desi means one tenth of sth.so on tenth of 0.54 is 0.054
