Answer:
The diameter of the oil molecule is
.
Explanation:
Mass of the oil drop = 
Density of the oil drop = 
Volume of the oil drop: v


Thickness of the oil drop is 1 molecule thick.So, let the thickness of the drop or diameter of the molecule be x.
Radius of the oil drop on the water surface,r = 41.8 cm = 0.418 m
1 cm = 0.01 m
Surface of the sphere is given as: a = 

Volume of the oil drop = v = Area × thickness


The thickness of the oil drop is
and so is the diameter of the molecule.
Answer:
b). silver (Ag)
Explanation:
If you look at the periodic table, you just need to look at the atomic number of the element, because the atomic number tells you how many protons there are in the nucleus of the element.
But do be careful because some periodic tables have the molar mass at the top left corner, but the one I use has the atomic number at the top left corner, so make sure you look for the atomic number and not the molar mass.
