please question 4 is important

Recrystallization of acetanilide Initial Meting Fail Melting Weight Terg. Temp. 3.1 108 Melting Compound Range Crude Acetanilide Pure Acetanilide 114 116 Weight of (watch glass + filter paper) - 43.713 Weight of watch glass + filter paper precipitate) = 45588 1. Based on data provided in this experiment Calculate acetanilide recovery 5 2. Calculate the error for the melting point of the purified acetanilide 3. Based on your obtained data, indicate whether you acquired more purified acetanilide or not? Why? (Hint: Sharp MP range means pure sample, Broad range means Imoure Sample). 4. Suppose you did not get crystals during this experiment. Answer the following a) in which step are you? ) In your opinion, What the reason for that? How could overcome that
