Calculate the density of nitrogen gas, in grams per liter, at stp.

lesantik [10]

Standard temperature is 273 K

Standard pressure is 1 atm

We use the ideal gas equation to find out density of nitrogen gas in g/L

Ideal gas equation:

$PV = nRT\\ PV = (\frac{Mass}{Molar mass)}RT\\ P(Molar mass) = (\frac{Mass}{Volume})RT\\ \frac{Mass}{Volume}=\frac{P(molar mass)}{RT} \\ Density = \frac{P(Molar mass)}{RT}$

Molar mass of $N_{2} = 28 g/mol$

Pressure = 1 atm

Temperature = 273 K

$Density = \frac{(1atm)(28 g/mol)}{(0.08206 \frac{L.atm}{mol.K})(273 K)}$

= 1.25 g/L

Therefore, density of nitrogen gas at STP is 1.25 g/L

When the stabilized state of an equilibrium system is altered, further chemical reactions begin until a new equilibrium is reach

Nezavi [6.7K]

The answer is a. True. This is also known as the Le Chatelier's principle or The Equilibrium Law which states that if a chemical reaction is at equilibrium and then experiences changes in the condition of the reaction such as changes in concentration, pressure, or temperature of products or reactants, the system will naturally shift to achieve a new equilibrium state.
