2.04 atm is the pressure of the nitrogen gas in the container when 0.316 mol sample of nitrogen gas, N2 (g), is placed in a 4.00 L container at 315 K.
Explanation:
Data given:
moles of nitrogen gas, n = 0.316
volume of the nitrogen gas, V = 4 litres
temperature of the container of nitrogen gas = 315 K
R (gas constant) = 0.08201 Latm/mole K
Pressure of the nitrogen gas on the container, P = ?
from the data given, we will apply ideal gas law equation to calculate the pressure on the nitrogen gas:
PV = nRT
Rearranging the equation,
P =
P =
P = 2.04 atm
The pressure of the nitrogen gas in the container is 2.04 atm.
Answer:
Reactant : A combustion of hydrocarbon.
Explanation:
It is known that when hydrocarbons are involved in combustion, they produce carbon dioxide and water.
CxHy + (x+y/4)O2 ===> xCO2 + y/2H2O
1 mole --------------- 6.02 x 10²³ atoms
( moles iron) -------- 5.0 x 10²⁵ atoms
( moles iron ) = 5.0 x 10²⁵ x 1 / 6.02 x 10²³
moles iron = 5.0 x 10²⁵ / 6.02 x 10²³
= 83.05 moles of iron
hope this helps!
