What is the mass percentage aluminum in this alloy?
A 0.250- sample of a magnesium-aluminum alloy dissolves completely in an excess of HCl. When the liberated H2 is collected over water at 29 degrees Celsius and 752 torr , the volume is found to be 341 mL . The vapor pressure of water at 29 degrees Celcius is 30.0 torr . What is the mass percentage of aluminum in this alloy?
