    If 2.00 g of element G reacts with 5.00 g of element M to produce 7.00 g of a compound with the formula G3M2, what is the atomic mass of G if the atomic mass of M is 135.0 amu? Answer is 36 amu but why

    I am supposed to find the percent abundancies of two isotopes. I am given the masses of both isotopes, along with the atomic mass. (This is a fictional element with only those two isotopes.) I am not given percentages for either isotope... how do I solve

    The steps to getting the answer. A certain metal oxide has the formula MO where M denotes the metal. A 39.46g sample of the compound is strongly heated in an atmosphere of hydrogen to remove oxygen as water molecules. At the end, 31.70g of the metal is
