Kepler's three laws of planetary motion can be stated as follows: (1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. (2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time. Third law of Kepler. The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. This captures the relationship between the distance of planets from the Sun, and their orbital periods.

Answer:
V = 44.83 L
Explanation:
Given data:
Mass of fluorine = 76 g
Temperature = 0°C (0°C + 273 = 273 K)
Pressure = 101.3 Kpa ( 101.3 / 101 = 1 atm)
Volume of fluorine = ?
Solution:
Number of moles of F = Mass/ molar mass
Number of moles = 76 g/ 38 g/mol
Number of moles = 2 mol
Volume of fluorine:
PV = nRT
V = nRT/ P
V = 2 mol × 0.0821 atm. L/ mol. k × 273 k / 1 atm
V = 44.83 L. atm / 1 atm
V = 44.83 L
