In an electrolysis experiment, the current used was 2.15 amp and the reaction was ran for 505 seconds. The temperature of the water was measured to be 299 K and the volume of O2 gas collected was 65.4 mL. The pressure after all corrections were made was 1.01 atm. Calculate the Avogadro’s number using the provided data.

When rolling two dice, the probability that the up faces sum to 7 is 1/6.  Suppose you are playing craps and the shooter (the person who rolls the dice)  has rolled (using fair dice – not cheating) something other than 7 on the last twenty rolls. What is the probability that the shooter  rolls a 7 on the next roll?

Calculate the concentration of a KMnO4 solution if the titration of a 10 mL sample required 45.0 mL of a H2C2O4 solution with a concentration of 0.350 M to reach the endpoint. 6 H+ + 2 MnO4⁻ + 5 H2C2O4  →                                                         2 Mn2+ + 8 H2O + 10 CO2
