How many moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100.0 degrees Cel
o-na [289]

1.137448506 mol moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100.0 degrees Celsius.

<h3>What is an ideal gas equation?</h3>

The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas. The terms are: p = pressure, in pascals (Pa). V = volume, in m^3.

We apply the formula of the ideal gases, we clear n (number of moles); we use the ideal gas constant R = 0.082 l atm / K mol:

PV= nRT

Given data:

P=100.0 kPa =0.986923 atm

T=100 degree celcius= 100 + 273 =373 K

V=35.5 L

Substituting the values in the equation.

n= \frac{\;0,98 \;atm \;X \;35,5 \;L }{\;0,082\;atm / \;K mol \;X \;373 K}

n= 1.137448506 mol

Hence, 1.137448506 mol moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100.0 degrees Celsius.

Sloan [31]

Answer:

North Korea (The Korean War).

Explanation:

When Korea was liberated from Japanese control at the end of the Second World War, the United States and the Soviet Union agreed temporarily to divide Korea at the 38th parallel of latitude north of the equator. This division resulted in the formation of two countries: communist North Korea (supported by the Soviets) and South Korea (supported by the United States).

Assume the diameter of a neutral helium atom is 1.40 × 102 pm. Suppose that we could line up helium atoms side by side in contac
Damm [24]

Answer:

4.4285\times 10^8 many atoms would it take to make the distance 6.20 cm from end to end.

Explanation:

Diameter of the helium atom =  d=1.40\times 10^2 pm

Let the number of atoms required to make the distance 6.20 cm be n.

d\times n= 6.20 cm =6.20\times 10^{10} pm

1.40\times 10^2 pm\times n=6.20\times 10^{10} pm

n=\frac{6.20\times 10^{10} pm}{1.40\times 10^2 }=4.4285\times 10^8

4.4285\times 10^8 many atoms would it take to make the distance 6.20 cm from end to end.
