a core of protons and neutrons surrounds by electrons
Density is the mass of compound divided by its volume can be shown as follows:


40 mL of snow having 20 g of mass calculated from density.
Now, 10 cm of snow = 3.93 inches = 20 g
As, 10 inches of rain will produce 11 inches of ice as the volume of ice is bigger than rain water.
10 inches rain = 11 inches snow
3.93 inches of snow produced by

Thus, 3.57 incehs of rain produces by 10 cm snow.
