Question 269694

Phosphoric acid can be prepared from phosphorus triiodide according to the reaction:

    Pl3 (s)  +  H2O(l) ———–> H3PO3(aq) + HI(g)

If 150 g of PI3 (MM = 411.7 g/mol) is added to 250 mL of H2O (g/mol), d = 1.00 g/mL), Identify which will be limiting and excess reagents.

How many grams of H3PO3 (MM = 97.99 g/mol) will be produced theoretically?
