The kinetic energy of translation of the molecules in 50 g of CO ₂ gas at 17^ C is

Options

  1. A4205.5 J
  2. B4102.8 J
  3. C3582.7 J
  4. D3986.3 J

Correct answer

B. 4102.8 J

Step-by-step solution

Kinetic energy of translation = 3 2 n R T aligned & n= 50 ~g 44 ~g = 25 22 ~mol & T=17^ C =290 ~K aligned Kinetic energy of translation aligned & = 3 2 ( 25 22 )(8.3)(290) J & =4102.8 ~J aligned
