The electron dot structure would look like this :
Answer: The pressure of nitrogen will be 2.0 atm
Explanation:
According to ideal gas equation:
P = pressure of gas = 1.0 atm
V = Volume of gas = 10.0 L
n = number of moles = ?
R = gas constant =
T =temperature =
Now again using ideal gas equation :
Thus pressure of nitrogen will be 2.0 atm
