Question

10 g of ethanol is dissolved in 50g of water calculate the mole fraction of each components

Answer 1

Answer:

mass of ethanol =10 g

mass of ethanol =10 g molar mass [C2H5OH]=46

mass of ethanol =10 g molar mass [C2H5OH]=46mass of water = 50 g

mass of ethanol =10 g molar mass [C2H5OH]=46mass of water = 50 gmolar mass of H2o = 18

mass of ethanol =10 g molar mass [C2H5OH]=46mass of water = 50 gmolar mass of H2o = 18moles of C2H5OH= 10 ÷46

mass of ethanol =10 g molar mass [C2H5OH]=46mass of water = 50 gmolar mass of H2o = 18moles of C2H5OH= 10 ÷46 =0.22 mol

mass of ethanol =10 g molar mass [C2H5OH]=46mass of water = 50 gmolar mass of H2o = 18moles of C2H5OH= 10 ÷46 =0.22 molmoles of H2O = 50÷ 18

mass of ethanol =10 g molar mass [C2H5OH]=46mass of water = 50 gmolar mass of H2o = 18moles of C2H5OH= 10 ÷46 =0.22 molmoles of H2O = 50÷ 18 = 2.78 mol.
