Thank you for the opportunity to help you with your question!

mass of MgCl2=24+35.5*2 =95g

mass of BaCl2=137.3+35.5*2=208.3g

mass of P2O5=30.97*2+16*5=141.94 g

mass of AlCl3=26.98+35.5*3=133.3


so the answer is AlCl3

Please let me know if you need any clarification. I'm always happy to answer your questions.
