How to go from mg to moles

WebSubstitute all known values for the calculation of molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M. You can also use the molarity calculator for mass concentration and molar masses. Simply enter the values that you are interested in and let it do all of the work. WebThe molecular weight of O2 is 32.0 g/mol, so 4.16 * 10^-4 mol O2 = .013 g O2 = 13.3 mg O2. If the water in which the O2 is dissolved is pure H2O (not sea water) then the concentration is 13.3 mg O2 / 1000 mg H2O = 13.3 ppt dissolved O2. So 10 mL dissolved oxygen/L water = 13.3 dissolved oxygen mg/L water. Mike Evans.
