WebOct 14, 2013 · Reaction equation: HX +NaOH ----> H2O + NaX 0.0688L x 0.750 M = 0.0516 moles OH -. That is also the moles of H +. Because HX is in a 1:1 ratio, the moles of H + is the same as the moles of HX. For example, if you have one mole of NaCl, you then have one mole of sodium ions and one mole of Chloride ions. WebThe procedure to use the molar mass calculator is as follows: Step 1: Enter the chemical compound in the respective input field. Step 2: Now click the button “Calculate Molar Mass” to get the result. Step 3: Finally, the molar mass of the chemical compound will be displayed in the new window. chrysler 200 remote start disabled
