Answer» For mole Fraction:-No. of MOLES of H2SO4=95.8/98=0.9776No. of Moles of H2O= 4.2/18=0.2333Mole Fraction=\frac{moles of H2SO4}{TOTAL moles} TotalmolesmolesofH2SO4 =0.8073For Molarity:-VOLUME of acid=100/1.91=52.3560 cm^3molarity= \frac{95.8}{98}* \frac{1000}{52.3560} 9895.8 ∗ 52.35601000 =18.6712 |
