Our quality control department is being moved to a different location and will not be able to handle any projects for a few weeks. It has come to our attention that GenChemCo at Colorado Mountain College has acquired an excellent reputation as a problem solving chemistry laboratory facility and we would like you to conduct the following investigation for us:
The sales of our primary product "Gourmet Popcorn" seems to be losing market share and a number of seemingly unknown brands are creating serious competition. Please, conduct the following research:
1.) Determine the percent by mass water content of our brand and compare it to the competitors' brands.
2.) Determine the kernel density of each brand and relate it to water content
3) Correlate the kernel size with density and water content.
Determine the partial pressure. Calculate the total pressure and volume in liters at STP of Nitrogen, Helium and Neon mixture.
