Answer:
<h3>The answer is 0.03 moles</h3>
Explanation:
To find the number of moles given the number of entities we use the formula

where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 2 × 10²² molecules of water
We have

We have the final answer as
<h3>0.03 moles</h3>

the elasticity of gas particle collisions, there is no energy loss when the particles pass one another. Gases are composed of a very large number of small particles, which spread out and avoid contact with one another.
<h3>Which of the following gas postulates from the kinetic molecular theory best explains why pressure exists in gases?</h3>
As the quantity of gas particles in the container rises, so does the frequency of wall interactions and subsequently the pressure of the gas. The average kinetic energy of a gas particle is exclusively dependent on the temperature of the gas, says the theory's final postulate. As the volume of gas particles inside the container grows, more of them will collide with the walls, increasing the pressure and the frequency of collisions.

You can solve this by using the equation (P1V1/T1) = (P2V2/T2). Plug in 0.50 atm for P1, leave V1 as the unknown, and plug in 325 K as T1. Then substitute 1.2 atm for P2, 48 L for V2, and 320 K for T2. Solve for V1, which is 117L, but since you round using two sig figs, your answer is C, 120 L. Hope this helps!
