The relative atomic weight of a metal can be determined by converting it to its metal oxide. In one such determination 1.00 g of metal X was burnt in oxygen to form 1.40 g of its oxide,
XO. Using the know atomic weight for oxygen and these results, the atomic weight of X is
a. 1.00 g/mol
c. 40.0 g/mol
b. 16.0 g/mol
d. 80.0 g/mol
