Answer:
14.9 g is the ideal yield of Cu(NO₃)₂
Explanation:
Reactants for the reaction: Cu and AgNO₃
Products: Copper nitrate and Ag
The balanced reaction is: Cu(s) + 2AgNO₃(aq) → 2Ag (s) + Cu(NO₃)₂
As the silver nitrate is in excess, the Cu will be the limiting reagent.
We convert the mass to moles → 5.05 g . 1 mol/ 63.55 g = 0.0794 moles
Ratio is 1:1, so 0.0794 moles will produce 0.0794 moles of Cupper(II) nitrate. We convert the moles to mass, and that value will be the theoretical yield.
0.0794 mol . 187.55 g /1 mol = of Cu(NO₃)₂
The average distance a gas particle travels between collisions (with the wall or another particle is called the mean free path.
According to the kinetic theory of gases, the particles of a gas (atoms or molecules) have the highest kinetic energy and travel at high speeds. At standard temperature and pressure, a gas particle can reach speeds of about 470m/s.
Despite the high speeds gas particles travel, it still takes a while for the fragrance of an opened perfume to diffuse to the other end of the room. This is because when moving, the molecules do not have a free path. They constantly collide with other particles and the walls of the container and change direction randomly. The average distance a single particle can travel without colliding with other particles, or the wall of the container is called the mean free path.

Density of liquid= 
.
so, density of liquid= 
= 1.2 gm/cm³.
So, if 1 mole occupies 22.4 L, the imediate conclusion is that a bigger number of moles will occupy more than 22.4 L, and a smaller number of moles will occupy less than 22.4 L. In your case, 3 moles of gas will occupy 3 times more volume than 1 mole of gas
