Question

what is Normality of 0.1381m NAOH​

Answer 1

Explanation:

For NaOH, normality is the same as molarity. It is reasonable to assume that 10 percent NaOH is on a w/v basis so that for 1000 mL of water you have 100 g of NaOH. The molecular weight of NaOH is 40 g/mole. So, 100 g corresponds to 2.5 moles. In 1 L of water (1000 mL) this is 2.5 M or 2.5 N.
