Aplanet has a surface temperature of 95.0 k and an atmospheric pressure of 1.60 atm. if 4.87 l of atmosphere has a mass of 28.6 g, what is the average molar mass of the atmosphere? use r=0.08206l atmmol k for the gas constant. your answer should include three significant figures.

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
