| Chemistry help?!!?!?
Questions 17. One atomic mass unit (u) is the approximate mass of a proton or a neutron. This mass is equal to 1.66 * 10^-24 g. How many atomic mass units are in one gram? 18. If an atom has a mass of 197 u, find the mass (in g) of a mole in these atoms. Please explain in simple terms, because I do not understand at all. If you need more info let me know! I am so confused and frustrated and very upset!      |
