Consider a 0.300 M solution of NaOH? Calculate the molality of NaOH. (Assume the density of the solution is the same as the density of pure water.) Assume that you have 1 L of solution: Mass of water = mass of solution – mass of NaOH = 1000 g – (0.300 mol)(40 g/mol) = 1000 g – 12 g = 988 g. Molality = 0.300 mol/0.988 kg = 0.304 m

Yeast solution should be anywhere from 50 to 200 ml of water for each packet. Hydrogen peroxide should be anywhere from 100 to 500 ml of water for every 10 ml of hydrogen peroxide. One method to time the rate of the reaction is to fill one test tube about 3/4 full with the hydrogen peroxide solution.

Except for substances in the gaseous state or solution, reactions occur at the boundary, or interface, between two phases. The greater surface area exposed, the greater chance of collisions between particles, hence, the reaction should proceed at a much faster rate. Ex. coal dust is very explosive as opposed to a piece of charcoal.
