When an element, e, is burned in air, the compound e4o10 is formed. assume that one experiment showed that 0.744 g of e produces 1.704 g of e4o10. use this information to determine the ratio of atomic masses of e and e4o10, and then use the atomic mass of oxygen to determine the atomic mass of e and identify the element for which e stands. (remember: atomic mass and molar mass are numerically equivalent.) (hint: there isn’t enough space below to perform all of the required calculations. you should brainstorm and consider how mass, molar mass, and the ratio of elements that can be determined from the chemical formula are related to each other. try to "see" the connections between these concepts.)
