Sagot :
A solid sample has a MP of 133 - 137°C. one can conclude about the sample is It is relatively impure.
the temperature at which a compound completely melts is called as melting point but generally we don't observe a melting point rather a range is observed if range more than 20 C is observed generally it's said that it's impure an impure solid melts over a wide range and at a temperature lower than that of the pure solid. so since the last value 139 0 C must be the reported value when you must have seen it completely melting so it's melting point should be this only .
