In class, students were given the following problem: "aluminum satellite dishes resist corrosion because aluminum reacts with oxygen gas to form a coating of aluminum oxide (al2o3). what is the mass of al2o3? "
a) sally solved the problem by first finding the molar mass of aluminum oxide. she calculated the molar mass of al2o3 as 43.0 g/mol. this is not the correct molar mass however. what did sally do wrong?
b) after finding the molar mass of al2o3, jacob set up the following conversion. (i'll add a pic)
is this the correct set up for the problem?
