A student places a 2.50 gram sample of magnesium metal in a bottle and fits the bottle with a 2-hole stopper as shown in the diagram below. Excess hydrochloric acid is added to the bottle causing an exothermic chemical reaction generating hydrogen gas. As the reaction proceeds, the gas travels through the tubing to an inverted bottle filled with water, displacing the air as the hydrogen gas is collected. Mg(s)+2HCl(g)=MgCl2(s)+H2(g)

Using the balanced equation above, calculate the volume hydrogen gas produced in the experiment at STP.

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?
