Answer:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
n is the number of moles of the compound
Mass of calcium nitrate = 54.3g
Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
Get the required molarity;
Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
