A student is trying to run an experiment that uses magnesium oxide, but he doesn't have any magnesium oxide available. What he DOES have is magnesium and oxygen, so he can synthesize the magnesium oxide he needs according to the equation below. How many grams of magnesium will the student need to use if his experiment requires 3.37 moles of magnesium oxide? Remember to round your answer to the nearest 0.01 and include units. HELP PLEASe

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.
