Answer from: zhellyyyyy

Considering the definition of STP conditions, 2.02 moles of N₂ gas are in the container.

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

You can apply the following rule of three: if by definition of STP conditions 1 mole of N₂ occupies a volume of 22.4 liters, how many moles of N₂ occupy a volume of 45.2 L?

$amount of moles=\frac{45.2 Lx1 mole}{22.4 L}$

amount of moles= 2.02 moles

Finally, 2.02 moles of N₂ gas are in the container.

Answer from: milkshakegrande101

The number of moles of N₂ gas in the container is approximately 2.02 moles

Explanation:

We re told that;

Volume of container = 45.2 L

Container Content is N₂, nitrogen gas at STP, Standard Temperature and Pressure

Standard Temperature = 273.15 K

Standard Pressure = 1 atmosphere

We can find the number of moles from the universal gas equation as follows;

Universal gas equation: P·V = n·R·T

Therefore;

$n = \frac{P \times V}{R \times T}$

Where:

n = Number of moles

P = Pressure = 1 atmosphere

V = Volume = 45.2 L

T = Temperature = 273.15 K

R = Universal Gas Constant = 0.08205 L·atm/(mol·K)

Plugging in the values gives;

$n = \frac{1 \times 45.2}{0.08205 \times 273.15 } = 2.01678 \ moles$

Therefore, the number of moles of N₂ gas in the container = 2.01678 moles or ≈ 2.02 moles.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
