Explanation:
Answer:
The surface-to-volume ratio of a C-60 fullerene is 3:77.
Explanation:
Surface area of sphere = 
Volume of the sphere = 
where : r = radius of the sphere
Radius of the C-60 fullerene sphere = r = 77 pm
Surface area of the C-60 fullerene =
...[1]
Volume area of the C-60 fullerene =
..[2]
Dividing [1] by [2]:


The surface-to-volume ratio of a C-60 fullerene is 3:77.
Answer:
Explanation:
mass of the reactant = mass of the product
15.31 + 1.50 = 16.81g
