Calculate the amount of H2O2: Using the balanced equation, calculate the number of moles of H2O2 present in the initial solution. Calculate the molar mass of H2O2 and determine the grams of H2O2 present in the initial solution. 5. Calculate the mass percent of hydrogen peroxide: Using the mass of H2O2 calculated above and the initial mass of the H2O2 solution, calculate the mass percent H2O2 in the initial solution. 6. Calculate the percent error: The accepted value for the concentration of hydrogen peroxide that is readily available at grocery stores and pharmacies is 3% by weight.

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.
