10g of ethanol dissolved in 50g of h2o calculate the mole fraction ethanol |
|
Answer» Here is your answer 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.Hope this would be helpful to you. |
