A new engine is being designed that will carry 5.430 x 102 kilograms of methane, CH4, on board. How many liters of gaseous oxygen needs to be carried on board to ensure complete combustion? The oxygen will be stored at 3.500 atm of pressure and -170.84 °C. Use four significant figures in your answer. Hint: write out the balanced chemical reaction. Assume the gas behaves ideally. (If you don't know don't answer. It takes up the points I worked really hard for for people who work equally as hard to help me understand these concepts)

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
