Two sample of gases '1' and '2' are taken at same temperature and pressure but the ratio of number of their volume is V1:V2 = 2:3. What is the ratio of the number of moles of the gas sample?

Correct answer: D. 2:3

  • A. 3:2
  • B. √2 :√3
  • C. 4:9
  • D. 2:3

Explanation

To determine the correct ratio, we can use the Avogadro's Law, which states that equal volumes of gases at the same temperature and pressure contain an equal number of molecules.Since the volumes of the gases are given as V1:V2 = 2:3, the ratio of the number of moles (n1:n2) will also be 2:3. This means that the correct option is d) 2:3, which represents the ratio of the number of moles of the gas sample.Hence, the correct option is d) 2:3, which represents the ratio of the number of moles of the gas sample.

About Fluid Dynamics

Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
