What is the molarity of the solution formed by mixing 0.20mol of sodium hydroxide with enough water to make 150 ml of solution?

Molarity is defined as the number of moles of solute in 1 L of solution 
number of NaOH moles present - 0.20 mol 
volume of solution - 150 mL 
since molarity is taken as number moles of solute in 1000 mL
if 150 mL contains - 0.20 mol 
then 1000 mL should contain - 0.20 / 150 x 1000 = 1.33 mol 
therefore molarity is 1.33 M

What are the choices?

Olá. porque a reação na temperatura é muito rapida a do copo : )
