Answer:
50°C
Explanation:
-Melting point is defined as the temperature at which a substance changes state from solid to liquid.
-For most chemical substances, the melting and freezing point are approximately equal.
-Hence, the freezing point for this substance is 323 K
#We convert the temperature as follows:
[tex]1\ K=\textdegree C+273\textdegree C\\\\\therefore 323K=323\textdegree C-273\textdegree C\\\\=50\textdegree C[/tex]
Hence, the freezing point of the substance is 50°C
