Chemistry help plz????

what is the normality of a solution containing 49g(1 equivalent) of H2SO4 in enough water to make 400ml of solution?

Answer:
N = 49X1000/98X400
=1.25
wt= N#V#eqwt/1000
49=N#400#(2+32+16#4)/1000
N#39200=49#1000
N=49000/39200
N=1.25
molecular weight of H2SO4 is (1*2+32+4*16) or 98.

normality= (49/98)/(400/1000) =1.25
