Donna was studying the following reaction for a stoichiometry project: s(s) + 3 f2(g) → sf6(s) she wondered how much she could obtain if she used 3.5 g of fluorine. what mass of sf6(s) would she obtain from the calculation using this amount of fluorine?

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
