Answer:
[KI] = 0.17 M
Explanation:
We determine the moles of solute:
Mass / Molar mass → 4.73 g / 166 g/mol = 0.0285 moles
Molarity (mol/L) is defined as moles of solute in 1L of solution
It is a sort of concentration
M = 0.0285 mol / 0.169L = 0.17 M
Instead of making the division (mol/L), we can also try this rule of three:
In 0.169 L we have 0.0285 moles of solute
in 1 L we must have ___ (1 . 0.0285) / 0.169 = 0.17 mol/L
3 cubic centimeters, Volume= density/ mass
Answer:
She overcame her disabilities to compete in the 1956 Summer Olympic Games, and in 1960, she became the first American woman to win three gold medals in track and field at a single Olympics. Later in life, she formed the Wilma Rudolph Foundation to promote amateur athletics.
Explanation:
C. two billiard balls colliding and bouncing off each other
Explanation:
From the given options, the most similar scenario to the type of collision depicted in the kinetic molecular theory is the collision of the two billiard balls bouncing off each other.
Here are some of the postulates of the kinetic molecular theory:
- A gas is composed of a large number of identical molecules moving at different speeds.
- The space occupied by the gas molecules is negligible compared to the volume of the container.
- Molecules move independently of one another
- Molecules collides with one another and with the walls of the container elastically i.e without loss of kinetic energy.
- The temperature of the gas is a measure of its average kinetic energy.
