1. How many g is present in a sample having 4.52 moles of CaCO3? 2. Methanol burns in air to form carbon dioxide and water: CH;OH + O2 → CO2+ H2O If 209 g of CH3OH are used up, what mass of H20 is produced? 3. Acetic acid (CH3COOH) can be produced based from the reaction: CH;COOC,H5 + H20 → CH;COOH + C2H5OH If there are 344.5 g of CH;COOC,H5 and 165.8 g of H20 How many moles of acetic acid will be produced? b. Calculate the percent yield if 125 g of acetic acid was produced а. 4. A sample containing 58.51 g manganese (Mn) is treated with an excess of sulfuric acid (H2SO4) to form manganese sulfate (MnSO4) and molecular hydrogen (H2). If 81.52% of manganese sulfate was produced experimentally, calculate the actual vield.

1. How many g is present in a sample having 4.52 moles of CaCO3? 2. Methanol burns in air to form carbon dioxide and water: CH;OH + O2 > CO2 + H20 If 209 g of CH;OH are used up, what mass of H20 is produced? 3. Acetic acid (CH3COOH) can be produced based from the reaction: CH;COOC2H5 + H2O → CH;COOH + C2H,OH If there are 344.5 g of CH3COOC,H5 and 165.8 g of H20 How many moles of acetic acid will be produced? b. Calculate the percent yield if 125 g of acetic acid was produced а. 4. A sample containing 58.51 g manganese (Mn) is treated with an excess of sulfuric acid (H2SO4) to form manganese sulfate (MNSO,) and molecular hydrogen (H2). If 81.52% of manganese sulfate was produced experimentally, calculate the actual yield.
