The enzyme "catalase" catalyzes the decomposition of hydrogen peroxide by the exothermic reaction:
H2O2 (aq) → H2O (l) + ½ O2 (g)
Estimate the minimum detectable concentration of hydrogen peroxide if a small amount of catalase (a solid) is added to a hydrogen peroxide aqueous solution in a calorimeter. Assume that a temperature rise of 0.02°C can be distinguished. You can use a heat capacity of 4.184 kJ kg⁻¹ K⁻¹ for the hydrogen peroxide solution.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
