Question

calculate the normality of NaOH if 0.4 of NaOH is dissolved in 500 ml of the solution

​

Answer 1

Explanation:

Once gram equivalent weight is understood, it is easier to understand the equation for normality:

Normality (N) = m /V × 1 / Eq.

Normality (N) = m /V × 1 / Eq.

m = 1 eq/L × 1 L × 40.00 g/eq ; therefore m = 40 g.
