Question

equivalent weight of H3PO4 IS

Answer 1

Hey there! 
_________________________________________

3H ====> 3*1=3 g

P ======> 31 g 

4 O ======> 4* 16 = 64 

Molecular mass of H3Po4 = 3+31+64=98 g

Equivalent weight = Molecular mass / Number of replaceable hydrogens. 

= 98/3

= 32.66

equivalent weight of H3PO4 is 32.66 g
hope helped!

Answer 2

Hi friend!!

Molecular mass of H₃PO₄ = 3(1) + 31 + 4(16)
= 3+31+64
= 98

We know,

Equivalent weight = molecular mass/no.of replaceable hydrogens
Equivalent weight of H₃PO₄ = 98/3
= 32.6
