Use the equation below to calculate the following: i (a) the moles Ca3(PO4)2 produced from 3.5 mol Na3PO4 3 Ca(NO3)2(aq) + 2 Na3PO4(aq) → Ca3(PO4)2(s) + 6 NaNO3(aq) i Incorrect. Did you use the balanced chemical equation to determine the mole to mole ratio? i ! mol Ca3(PO4)2 (b) the moles NaNO3 produced from 0.65 mol Ca(NO3)2 Incorrect. Did you use the balanced chemical equation to determine the mole to mole ratio? ! mol NaNO3 Incorrect. Did you use the volume and the molarity to determine the number of moles of Ca(NO3)2 present? (c) the moles Na3PO4 required to react with 3.39 L of 0.190 M Ca(NO3)2 ! mol Na3PO4
(d) the grams of Ca3(PO4)2 that can be obtained from 135 mL of 0.735 M Ca(NO3)2 i Incorrect. Did you multiply the volume of Ca(NO3)2 by the molarity to determine the number of moles that are reacting? i ! g Ca3(PO4)2 (e) the volume of 0.17 M Na3PO4 needed to react with 24 mL of 0.70 M Ca(NO3)2 i Incorrect. Did you use the molarity and volume of Ca(NO3)2 to determine how many moles of Ca(NO3)2 are reacted with Na3PO4? ! mL Na3PO4 Incorrect. Did you first determine the number of moles of Ca(NO3)2 that would react with the given amount of Na3PO4? (f) the molarity (M) of the Ca(NO3)2 solution when 36.9 mL react with 44.3 mL of 5.5 M Na3PO4 ! M Ca(NO3)2
