    mass is 4.57 g

    Explanation:

    Ca (OH) ₂ solution consists of Ca (OH) ₂ solute molecules and solvent and we are asked to find the mass of Ca (OH) ₂ in the solution

    number of moles of Ca (OH) ₂ is - 0.0787 mol

    molar mass of Ca (OH) ₂ is - 58.093 g/mol

    we can use the following equation

    number of moles = mass of Ca (OH) ₂ / molar mass of Ca (OH) ₂

    rearranging the equation

    mass of Ca (OH) ₂ = number of moles x molar mass

    mass = 0.0787 mol x 58.093 g/mol = 4.57 g

    mass of Ca (OH) ₂ is 4.57 g
