Molecular weight of sulfuric acid (H 2 SO 4) = 98. Each ball-and-stick model incorrectly shows the electron and molecular geometry of a generic molecule. An experimental determination of the molecular mass reveals that a molecule of benzene contains six carbon atoms and six hydrogen atoms, so the molecular formula for benzene is C 6 H 6 (Figure 2. 3 °F) at atmospheric. Likewise, catalase has one of the highest turnover numbers of all enzymes; one catalase. Compared to water (H2O), hydrogen peroxide is endowed with an extra oxygen that provides it with strong oxidizing power and gives it the capability to get rid of stains and. Most cells in the body contain catalase, so when the tissue is damaged, the enzyme is released and becomes available to react with the peroxide. The chemical formulas on the left represent the starting substances, called reactants. The "Di" means there are 2 atoms of hydrogen.
