the decomposition of N2O5 in carbon tetrachloride proceeds as follows: 2 N2O5 -> 4 NO2 + O2. The rate law is first order in N2O5. At 64 degree celcius the rate constant is 4.82 x 10^ 3 s ^ -1.
To get an estimate of the number of beans in the jar you weigh six beans and obtain masses of 3.15, 3.12, 2.98, 3.14, 3.02, and 3.09 g . Then you weigh the jar with all the beans in it, and obtain a mass of 2082g . The empty jar has a mass of 6..
