A cylinder of Krypton has contains 17 L of Ar at 22.8 atm and 112 degrees celsisus. How many moles are in the cylinder?​
Arlecino [84]

Given :

A cylinder of Krypton has contains 17 L of Ar at 22.8 atm and 112 degrees Celsius.

To Find :

How many moles are in the cylinder.

Solution :

We know, by ideal gas equation :

PV = nRT\\\\n = \dfrac{PV}{RT}

Here, R is gas constant and R = 8.205 \times 10^{-5} \ m^3\ atm\ K^{-1} mol^{-1}

Converting all given in required units and putting in above equation, we get :

n = \dfrac{P\times V}{ R \times T}\\\\n = \dfrac{22.8 \times 0.017}{8.205\times (112+273)}\ moles\\\\n = 1.22 \times 10^{-4} \ moles

Hence, this is the required solution.

First, let's explain the variables. F means force, m means mass, and a means acceleration. F is measured in Newotns [N], mass is measured in kilograms [kg], and acceleration in measured in meters per squared second [m/s²].

Now let's mover on the first problem.

Given

m = 1000 kg

a = 3 m/s²

According to the second law of Newton, the force is equal to the acceleration multiplied by the mass.

F = am\\F = 3 * 1000\\F = 3000 N

The answer is 3000 N.

The second problem is smiliar.

Given

m = 70 kg

F = 250 N

We use the same formula from before, and use a bit of algebra to adapat it to our needs.

F = ma\\\frac{F}{m} = a\\a = \frac{F}{m}\\a = \frac{250}{70} \\a = 24\frac{1}{7} m/s^{2}

The answer is 24 1/7 s/m^2.
