Question

How many grams of P2O3 are needed to react with 248 g of NaOH ?

Answer 1

170.43g P2O3

Step-by-step explanation:

First write and balance the equation:

P2O3 + 4NaOH → 2Na2HPO3 + H2O

NaOH=39.997 g/mol P2O3= 109.945 g/mol

248g NaOH x 1 mol NaOH/39.997g NaOH x 1 mol P2O3/4 mol NaOH x

109.945g P2O3/ 1 mol P2O3 = 170.43g P2O3
