Write a program to determine the mass of oxygen gas (formula: O2, molecular weight = 32 grams per mole) in units of grams in a container. You may assume that the user will provide the volume of the container in units of gallons, the temperature in the container in degrees Celsius, and the pressure in the container in units of atmospheres. For your test case, you may assume that the user provides 1.25 gallons for the volume of the container,...

The molecular weight of a compound is typically indicated by the heaviest peak on a mass spectrum, which i presumed to correspond to the molecular ion (M*). For smaller compounds, the heaviest peak tends to also be the most intense peak. The lighter peaks in the spectrum result from fragmentation of the molecule into smaller ions. Since peak intensity correlates to the relative stability of the ions produced, the peaks of the ionized fragments can be more intense than the...
