SUMMARY
The mass of one mole of calcium nitrate, Ca(NO3)2, is calculated to be 164.1 grams. For 0.05 moles of Ca(NO3)2, the number of Ca2+ ions is determined using Avogadro’s number, resulting in 3.011 x 10^22 Ca2+ ions. Additionally, the number of moles of sodium chloride (NaCl) in 450 grams is calculated to be approximately 5.95 moles, based on its molar mass of 75.53 g/mol. The calculations confirm the accuracy of the first and last questions posed in the homework statement.
