Understanding Active Mass
Active mass in chemistry refers to the concentration of a species in a reaction mixture, often expressed in terms of moles per liter.
Calculating Moles of Nitrogen
To calculate the active mass, we first need to find the number of moles of nitrogen (N2) in 7 grams.
- Molar Mass of Nitrogen (N2): 28 g/mol (14 g/mol for each nitrogen atom)
- Moles of N2:
- Formula: Moles = Mass / Molar Mass
- Calculation: 7 g / 28 g/mol = 0.25 moles
Finding the Volume of the Container
The volume of the container is given as 2 liters.
Calculating Active Mass
Active mass (or concentration) is calculated using the formula:
- Active Mass (Molarity):
- Formula: Molarity = Moles / Volume (in L)
- Calculation: 0.25 moles / 2 L = 0.125 moles/L
Conclusion
The active mass of nitrogen in the container is:
- Correct Option: b) 0.125
This indicates that there are 0.125 moles of nitrogen per liter in the 2 L container, which reflects its concentration in the reaction mixture.
