Consider the following reaction:

2H2O2(aq)→2H2O(l)+O2(g)

The graph (Figure 1) shows the concentration of H2O2 as a function of time.
If the instantaneous rate of formation of O2 is 3.3*(10^-3) moles/(liters*seconds), then...
If the initial volume of the H2O2 solution is 1.5 L , what total amount of O2 (in moles) is formed in the first 50 s of reaction?
Express your answer using two significant figures.
