14.4 g of an element X react with oxygen to form24.0 g of a compound XO Which element is X?
A) Fluorine
B )Magnesium
C )Titanium
D ) Molybdenum
I knew it wasn’t mg bc thats a group 2 metal but like how would i get titanium
They tell you that there were 14.4 g of the metal and this reacted with oxygen to form 24.0 g of the oxide. From that, first work out how much oxygen was added to the metal and work out how many moles of oxygen atoms that is equivalent to.

So would the mass of oxygen added be 24.0-14.4? And then the moles just 9.6/32?
Might be a typo, i got the question at the end of this enthalpy booklet my teacher gave us
No, it's not a typo. "14.4 g of an element X react with oxygen to form 24.0 g of a compound XO. Which element is X?" You correctly determined that there are 0.6 mol of oxygen. You know that the mol of metal = mol oxygen Therefore mass of metal/mol metal gives relative mass.
