61.5 grams of Ca(OH)2 are needed to produce 500 ml of 1.66 M Ca(OH)2 solution. Details about mass can be found below.
The mass of a substance can be calculated by multiplying the number
of moles of the substance by its molar mass.
However, in this question, the number of moles in 500 ml of 1.66 M Ca(OH)2 solution must be calculated first.
no of moles = 1.66M × 0.5L
no of moles = 0.83moles
molar mass of Ca(OH)2 = 74.093 g/mol
mass of Ca(OH)2 = 74.093 × 0.83 = 61.5g
Therefore, 61.5 grams of Ca(OH)2 are needed to produce 500 ml of 1.66 M Ca(OH)2 solution.
