Question

40 g of naoh in 1000 ml of water equals _____ equivalent(s) of oh- .

Answer 1

The # of equivalents of OH in NaOH is the number of moles of OH divided by its valence.

Molar mass of the NaOH = 40 g/mol

# of moles of NaOH = 40 g/ 40 g/mol = 1 mol

Valence of OH = 1

# Equivalents of OH = 1 /1 = 1 equivalent.
