Question

A student prepares phosphorous acid by reacting solid phosphorous triiodide with water

PI₃(s) + 3 H₂O(l) → H₃PO₃(s) + 3 HI(g)

The student needs to obtain 0.359 L of phosphorous acid (d=1.651g/mL). The procedure calls for a 43.3 % excess of water and a yield of 70.8%. How much phosphorous triiodide should be weighed out?

Expert Solution
Step 1

The given equation is:

Chemistry homework question answer, step 1, image 1

volume of phosphorous acid = 0.359 L= 359 mL

density of phosphorous acid = 1.651 gram/ mL

so,

Chemistry homework question answer, step 1, image 2

Molar mass of phosphorous acid = 82 gram/mole

Then, determine the number of moles by dividing the mass by its molar mass.

so,
