Question: On the sunlit surface of Venus, the atmospheric pressure is 9.0 10 6 Pa, and the temperature is 740 K. On the earths surface

On the sunlit surface of Venus, the atmospheric pressure is 9.0 × 10⁶ Pa, and the temperature is 740 K. On the earth’s surface the atmospheric pressure is 1.0 × 10⁵ Pa, while the surface temperature can reach 320 K. These data imply that Venus has a “thicker” atmosphere at its surface than does the earth, which means that the number of molecules per unit volume (N/V) is greater on the surface of Venus than on the earth. Find the ratio (N/V)Venus/(N/V)Earth.
