Can someone redo my calculations for Stoichiometry and aPrecipitation Reaction lab and explain how you got that answer?Teacher is saying mine are incorrect and I need to fix forreport I am writing but I am not sure where or how iwent wrong.
Background info:
Na2CO3(aq) + CaCl2⋅2H2O → CaCO3(s) + 2NaCl(aq) + 2H2O(l)
Table thats incorrect below
Question 1 Data Table 1: Stoichiometry Values Initial: CaCl2+2H₂O (g) Initial: CaCl2+2H₂O (mol) Initial: CaCl₂ (mol) Initial: Na₂CO3 (mol) Initial: Na₂CO3 (g) Theoretical: CaCO3 (9) Mass of Filter paper (g) Mass of Filter Paper + CaCO3 (g) Actual: CaCO3 (9) % Yield: 1.0 0.0068 0.0067 0.0068 0.7209 0.68 1.00 1.62 0.62 91.17%
