50 mL of 10 N H_(2)SO_(4) , 25 mL of 12 N HCl and 40 mL of 5 N HNO_(3)were mixed together and the volume of the mixture was made 1000 mL by adding water. The normality of the resultant solution will be

Answer»

1 N
2 N
3 N
4 N

Solution :`N_(1)V_(1) + N_(2)V_(2) + N_(3)V_(3) = NV`
`10 xx 50 + 12 xx 25 + 5 xx 40 = N xx 1000` or, N = 1N
