To calculate the mass of MnCl2 isolated by the reduction of MnO2 with HCl, you need to first balance the chemical equation for the reaction:
MnO2 + 4 HCl -> MnCl2 + 2 H2O + Cl2
Then, use stoichiometry to determine the mass of MnCl2 produced. First, calculate the moles of HCl using its molar mass and mass given. Then, using the stoichiometric ratio from the balanced equation, determine the moles of MnCl2 produced. Finally, convert moles of MnCl2 to grams using its molar mass.
