The concentration of H_(2)SO_(4) in a botal labelled ''conc. Sulphuric – InterviewSolution

1.	The concentration of H_(2)SO_(4) in a botal labelled ''conc. Sulphuric acid'' is 18 M. The solution has a density of "1.84 g cm"^(-3). What is the mole fraction and weight percentage of H_(2)SO_(4) in this solution?
Answer» Solution :`"Conc. = 18 MOL L"^(-1)." Solute = 18 moles "=18xx98 g = 1764g,"Solution "=100cm^(3)=1840g.` `"Solvent "=1840-1764 = 76g` `"Mole FRACTION of "H_(2)SO_(4)=(18)/(76//18+18)=0.81" ,Weight "%=(1764)/(1840)xx1000=95.87.`
