Aballoon is a sphere with a radius of 5.0 m. the force of the air against the wall of loan is 45 n. what is the air pressure inside the balloon ? (surface area = 12.56 x radius 2, 1 pa = n/m^2)

When the pressure that a gas exerts

Which statement best describes the flow of energy in this scenario

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
