Molar mass of
HC2H3O2 = 1 + 12.2 + 1.3 + 16.2 = 60 g/mol-1
1 mol of HC2H3O2 -------------------> 60 g
1,26.10^-4 mol --------------------------> x g
x = 1,26.10^-4 . 60
x = 0,00756 g

1.26*10^(-4) mol HC2H3O2* (60 g HC2H3O2/ 1 mol HC2H3O2)= 7.56*10^(-3) g HC2H3O2.
The final answer is
7.56*10^(-3) g HC2H3O2
