sarajevo

Answer:

1.67 M

Explanation:

Molarity =  [tex]\frac{moles}{liter}[/tex]

Moles = [tex]\frac{mass}{molar mass}[/tex]

Given

Mass of KOH =  14 g

Molar mass of KOH =  56.1056 g/mol

Moles of KOH =  [tex]\frac{14 g}{56.1056 g/mol}[/tex] = 0.25 mol

Volume of solution = 150 ml = 0.15 L (1 L = 1000 ml)

Molarity = [tex]\frac{0.25 mol}{0.15 L }[/tex]= 1.67 M
