Answer:

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
