Question

The atmosphere of Mars is primarily CO2 with some nitrogen and argon and a few other trace elements • Carbon dioxide: 95.32 percent • Nitrogen: 2.7 percent • Argon: 1.6 percent • Oxygen: 0.13 percent • Carbon monoxide: 0.08 percent The atmosphere of Mars is much thinner than Earth's. The average surface pressure is only about 610 pascals (0.088 psi) which is less than 1% of the Earth's value. Space X is planning for humans to grow plants on Mars just by compressing the atmosphere. The Martian polar caps, minerals, and soil could all provide sources of carbon dioxide, in part, due to the presence of aragonite, CaCO3, which decomposes when heated to calcium oxide and carbon dioxide. CaCO3(s) --> CaO(s) + CO2(g) Calculate the mass of CaCO3 (MM= 100.09) in units of grams that must be heated in order to produce 7.44 L of CO2 in a sealed container at 267.72 K and a pressure of 0.070 atm. Report your answer to three decimal places and do not include units.
