Calcium with a mass of 526.32 g completely reacted with an unknown halogen, the mass of which is 500 g. Determine which halogen has reacted.
Ca + Hal2 = CaHal2
n (Ca) = m \ M = 526.32 \ 40 = 13.158 mol
n (Ca) = n (Hal2) = 13.158 mol at ur-u r-i
M (Hal2) = m \ n = 500 \ 13.158 = 38 g \ mol, which corresponds to F2
Answer: fluorine
