The formation of water according to the equation 2H2 + O2 + 2H20
shows that 2 molecules (made of 4 atoms) of hydrogen and 1 molecule (made of 2 atoms) of
oxygen produce 2 molecules of water. The total mass of the product, water, is equal to the sum of
the masses of each of the reactants, hydrogen and oxygen. What parts of Dalton's atomic theory are
illustrated by this reaction? What law does this reaction illustrate?

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
