Question

80 gm of sodium hydroxide is dissolved in 2dm³ of solution.calculate molarity of solution​

Answer 1

Molarity is a concentration term in which the no. of moles and the volume are related.

Molarity

(c)=

no. of moles(n)volume in L(V)

Here

n=10 g40 g/mol

V=500 mL=0.5 L Soc=nV=10 g40 g/mol×0.5 L=10 mol20 L=0.5 molar
