The power output of a laser is measured in units of watts (W), where one watt is equal to 1 one joule per second (1 W = 1 J. s-1) What is the number of photons emitted per second by a 1.00 mW nitrogen laser?
The wavelength emitted by a nitrogen laser is 337 nm.

Magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. trial 1: trial 2: data mass of empty crucible with lid trial 1: 26.688 trial 2: 26.681 mass of mg metal, crucible, and lid trial 1: 26.994 trial: 2 26.985 mass of mgo, crucible, and lid trial 1: 27.188 trial 2: 27.180
