A shipment from Earth to Mars contains a 50 gallon [gal] tank filled with an ideal gas. The molecular weight of the ideal gas is 15.9 grams per mole [g/mol]. NASA tells the astronauts on Mars that the tank and gas combined had an initial total mass of 5 kilograms [kg] and the pressure was 3 atmospheres [atm] before it left the Earth. During the trip, the temperature was kept constant at 20 degrees Celsius [°C]. When it arrives on Mars, the astronauts check the sensors and discover the pressure is 2.2 atmospheres [atm] and the temperature is 20 degrees Celsius [°C]. Based on this information, the astronauts determine that some of the gas leaked during shipment. Determine how much gas leaked from the tank in units of grams [g]. Gravity on Mars = 3.71 meters per second squared[m/s2].
