    5.84 M

    Explanation:

    First you have to convert grams of Ca (OH) 2 to moles,

    since molar mass is 74.093 g/mol, we divide the amount you have by the molar mass: (86.5 g) / (74.093 g/mol) = 1.1675 moles of Ca (OH) 2

    Then, knowing molarity is (moles / volume in liters), we have to convert 200 mL to liters, which is 0.200 L

    Putting it together, molarity = (1.1675/0.200) M = 5.84 M
