A backpacker wants to carry enough fuel to heat 2.5 kg of water from
25 °C to 100.0 °C. If the fuel she carries produces 36 kJ of heat per gram when it burns, how much fuel should she carry? (For the sake of simplicity, assume that the transfer of heat is 100% efficient.)
Gallium has only two naturally occurring isotopes, Ga-69 and Ga-71.
The mass of Ga-69 is 68.9256 amu, and the mass of Ga-71 is 70.9247 amu. Use the atomic mass of gallium to determine the relative abundance of each isotope in a naturally occurring sample.
Total Pressure
`Using both the ideal gas law and Dalton’s law of partial pressures, calculate the total pressure of a 1.00 L container at 25 degrees C that contains 32.0 g O2and 14.0 g N2(the 2’s here are subscripts). You must show all work to receive credit.
