The equivalent mass of the metal is 12 g/eq.

Explanation:

#"Initial equivalents of H"_2"SO"_4 = 0.050 color(red)(cancel(color(black)("L"))) × "1 eq"/(1 color(red)(cancel(color(black)("L")))) = "0.050 eq"#

#"Equivalents of NaOH" = 0.0142 color(red)(cancel(color(black)("L"))) × "1 eq"/(1 color(red)(cancel(color(black)("L")))) = "0.0142 eq"#

#"Unreacted equivalents of H"_2"SO"_4 = "equivalents of NaOH" = "0.0142 eq"#

#"Reacted equivalents of H"_2"SO"_4 = "(0.050 - 0.0142) eq" = "0.0358 eq"#

#"Equivalents of metal" = "equivalents of H"_2"SO"_4 = "0.0358 eq" = "0.43 g"#

#"Equivalent mass of the metal" = "0.43 g"/"0.0358 eq" = "12 g/eq"#
