The melting point of 2.0g sodium chloride is: 400C
What is melting point?
The temperature at which an idealized pure substance can coexist in both its liquid and solid phases is known as its melting point.
Given that,
Melting point of 4.0g sodium chloride=800C
Setting up a proportion:
[tex]\frac{4}{800}=\frac{2}{X}[/tex]
4X = 800*2
4X = 1600
X = 1600/4
X = 400
Therefore, the melting point of 2.0g sodium chloride is 400C.
