According to my teacher, it's easy, but for my whole class, it isn't. :P
Unknown element X combines with oxygen to form the compound XO2. If 44.0 grams of element X combines with 8.00 grams of oxygen, what is the atomic mass of element X?I'd appreciate the help and preferably a quick explanation, because no one understands it and our teacher is giving limited hints out. Thanks.
