Quizplus · Accepted Answer

The formula of ammonium phosphite is (NH4)H2PO3. The formula mass of ammonium is 18.04 amu, phosphorus is 30.97 amu, oxygen is 16.00 amu, and hydrogen is 1.01 amu. Therefore, the formula mass of ammonium phosphite is:

(18.04 + 30.97 + (16.00 x 3) + (1.01 x 8)) = 133.09 amu. Therefore, the correct answer is C.
