Expert Answer:

The space reaction space equation space is space

3 straight H subscript 3 PO subscript 2 space space rightwards arrow PH subscript 3 space space space plus space space space straight H subscript 3 PO subscript 3

Equivalent space weight equals space fraction numerator Molecular space weight over denominator straight n minus factor end fraction

straight n minus factor space equals fraction numerator No. space of space electrons space transfered space in space reaction space left parenthesis loss divided by gain right parenthesis over denominator total space no. space of space moles space in space balanced space reaction end fraction

F o r
3 straight H subscript 3 PO subscript 2 space space rightwards arrow PH subscript 3 space

The space number space of space gain space of space electrons space are space 4 space as space change space of space oxdation space state space is space from space plus 1 space to space minus 3.

therefore space straight n space equals space 4 over 3

Equivalent space weight equals fraction numerator 66 over denominator begin display style bevelled 4 over 3 end style end fraction

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals fraction numerator 66 cross times 3 over denominator 4 end fraction
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space
space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 49.5 space straight g
