Which statement(s) below are correct regarding Rutherford's gold foil experiment? Choose ALL that apply. a. The atom is mostly empty space
b. The mass and positive charge is concentrated in the center of the atom
c. Atoms contain a nucleus
d. Most alpha particles bounced off of the gold foil

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.
