37% weight of HCl and density is 1.1g/ml. find molarity of HCl
lculwhat is the equation for caating molar mass of non volatile solute
Energy changes in some chemical reactions can be used to deduce the energies of chemical bonds. Our understanding of the molecular basis of thermodynamic properties is extended when we ask why the enthalpy change for a reaction is what it is. We deduce,
