- .0380 of Mg strip reacted completely with 6 M HCL in the gas buret and 35.8 mL of hydrogen gas is collected over water at 20 c. The pressure of the "wet" hydrogen gas is adjusted to the outside atmospheric tempertature, a pressure of 747.50 torr. The vapor pressure of water at 20 c is 17.54 torr. using the volume of hydrogen gas collected and the universal gas law, PV = nRT, where R is the gas constant 0.08206 L•atm/mol•K, calculate the experimental number of moles of hydrogen produced.arrow_forwardA mixture of He and CO2 is placed in a 7.5L flask at 22C.
