White phosphorus reacts with chlorine and the product hydrolyses in the presence of water. Calculate the mass of HCl obtained by the hydrolysis of the product formed by the reaction of 62 g of white phosphorus with chlorine in the presence of water.

when white phosphorous react with chlorine:

P₄ + 6Cl₂ 4PCl₃

PCl₃ + 3H₂O H₃PO₃ + 4HCl ]*4

NET REACTION: BEFORE ADDING SECOND REACTION TO FIRST, MULTIPLY IT BY FOUR

P₄ +6Cl₂ +12H₂O 4H₃PO₃ +12HCl

Moles of white P= = 0.5mol

1mol of white P₄ produce HCl = 12mol

0.5 mol of white P₄ will produce HCl = 12*0.8 = 6mol

Mass of HCl = 6*36.5 = 219.0g
