If 1.63 times 10 negative 4 of helium dissolves in 100.0g of water, what is the concentration in parts per million

Achange in the number of neutrons in an atom will change an blank . when the number of protons changes in an atom, a new element will form.

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.
