Question

.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.

Definition Definition Any of various laws that describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. At a constant temperature, the pressure of a particular amount of gas is inversely proportional with its volume (Boyle's Law) In a closed system with constant pressure, the volume of an ideal gas is in direct relation with its temperature (Charles's Law) At a constant volume, the pressure of a gas is in direct relation to its temperature (Gay-Lussac's Law) If the volume of all gases are equal and under the a similar temperature and pressure, then they contain an equal number of molecules (Avogadro's Law) The state of a particular amount of gas can be determined by its pressure, volume and temperature (Ideal Gas law)
