Solution

The correct option is D $90$
Normality $= \frac{n u m b e r o f g r a m e q u i v a l e n t}{v o l u m e o f s o l u t i o n i n l i t r e}$
$\frac{n u m b e r o f g r a m e q u i v a l e n t}{v o l u m e o f s o l u t i o n i n l i t r e} N o r m a l i t y = \frac{m a s s o f s o l u t e}{e q u i v a l e n t m a s s} \times \frac{1000}{V o l (m l)} 0.1 = \frac{0.45}{e q . m a s s} \times \frac{1000}{100} e q . m a s s = \frac{0.45}{0.1} \times 10 e q . m a s s = 45 A s i t i s a d i b a s i c a c i d, s o m o l e c u l a r m a s s = 2 \times e q u i v a l e n t m a s s = 2 \times 45 M o l e c u l a r m a s s = 90$
