Websolutions are those that contain two or more chemical compounds in addition to the solvent. To make a complex solution with solid solutes, you treat each solute individually when determining the mass of that compound to add to the solution. For example, to make a five liter solution of 50 millimolar NaCl and ten millimolar tris-HCl, you WebAmount (in g) = Amount (in mol) x Molar Mass (g.mol-1) Sometimes the term “Dalton” is used for molecular mass. For example the molecular mass of glycine is 75 Da while the ... Converting M to g/L You have a 1 M solution of NaCl, what is the concentration in % (w/v)? 1 M = 1 mol / 1 L 1 mol of NaCl = 58.44 g.mol-1 Amount (in moles ...
