I think the answer is D (number 4)
The process of changing solid to liquid is known as fusion
Answer:
number of molecules =9.03×10^23
Explanation:
use the equation
n=number of molecules /Av.constant
make number of Molecules become the subject of the formula by multplying Av.constant on both sides of the equation,
number of molecules=n×Av. constant ,where Av.constant is 6.02×10^23
number of molecules=1.5mol×6.02×10^23
=9.03×10^23
