Astorage tank of water is contaminated with hexane. the hexane is measured to be 65 mg/l in the aqueous phase. the total pressure of the gas in the headspace (above the liquid) is 1.2 atm. calculate the concentration of hexane in the gas phase, in units of atm. then find the % (or fraction) of the gas that is hexane

If a || b and e || f, what is the value of y ?

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold
