Question

please help i dont understand


What would be the resulting molarity of a solution made by dissolving 31.3 grams of Ca(OH)2 in enough water to make a 1050-milliliter solution? Show all of the work needed to solve this problem.

Answer 1

apply the molarity formula: \(M=\dfrac{n_{Solute}}{L_{Solution}}\)

Answer 2

using gram given find mole of Ca(OH)2
mole= mass/ Mr
then use formula
Molarity= mole/dm3
so convert milliliters to dm3 and then substitute your readings to the equation
that't it :)
