If you mean ammonium hydrogen phosphate, #(NH_4)_2HPO_4" (ammonium biphosphate)"#, then there are #3.35# #mol# #"H atoms"#.

Explanation:

#"Moles of ammonium hydrogen phosphate"# #(49.2*g)/(132.06*g*mol^-1)# #=# #0.373*mol#.
Clearly, there are #9# #mol# #H# per #mol# #(NH_4)_2HPO_4#, thus #3.35*mol# #"hydrogen atoms"#.
