Solid methanol melting point
WebThe following steps are needed to calculate the heat required to melt solid methanol: Calculate the molar mass of methanol. Calculate the number of moles contained in 25.7g … WebDuring the recrystallization of the crude solid, the solid began to dissolve. However, not all of it dissolved. Once vacuum filtrated, the final product was left to cool, and this caused white crystals to crash out. These crystals weighed 4.03g. Lastly, the melting point was measured to give a range of 64.0-64.6 °C.
