If the atomic mass of an atom is 34 and the atom contains 13 protons, how many neutrons does the atom contain?

All of the following are part of the biosphere except

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.
