Answer: The total width of a crystal is 1.65 mm.
Explanation:
Horizontal length between the two molecules = 16.5 nm
Width of the molecules :
The total width of a crystal in millimeter=
The total width of a crystal is 1.65 mm.
Assuming that nitrogen gas is ideal, we can use the equation PV = nRT to relate first conditions to the second condition. At constant temperature, pressure and volume are indirectly related as follows:
P = k / V
k is equal nRT
P1V1 = P2V2
P2 = 101.325 ( 4.65 ) / .480 = 981.586 kPa
The answer is D, reactant.
