2 H2 + CO → CH3OH Methanol (CH3OH) can be produced through the reaction of carbon
monoxide and hydrogen gas in the presence of a catalyst. If 75.0 g of
carbon monoxide react to produce 68.4 g CH3OH, what is the percent
yield of CH3OH? (molar mass of CH3OH= 32.04g, CO= 28.01g)

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?
