Question

. What is the molarity of a solution in which 6.50 mol of NaOH is dissolved in

Answer 1

Answer:

For 6.50 mol NaOH -  1.44M.

For 6.50 g NaOH - C. 0.0361 M

Explanation:

For 6.50 mol NaOH.

Molarity = moles solute/L solution = 6.5 mol/4.5 L solution = 1.44 mol/L=1.44M

There is no such answer in given choices.

For 6.50 g NaOH

M(NaOH) = 23 + 16 + 1 = 40 g/mol

Molarity = 6.5g* 1 mol/40g *1/4.5L = 0.0361 mol/L = 0.0361 M

There is such answer. It is C.
