Question
10g of h2so4 is added into 20g of water. Calculate the mole fraction of h2so4
Answers
moles H2SO4 = 10 g / (molar mass H2SO4)
moles H2O = 20 g / (molar mass H2O)
mole fraction H2SO4 = moles H2SO4 / (moles H2SO4 + moles H2O)
moles H2O = 20 g / (molar mass H2O)
mole fraction H2SO4 = moles H2SO4 / (moles H2SO4 + moles H2O)
