How many mol of nitrogen monoxide gas (N2) are in a 1.49 L container at standard temperature and pressure?

Nitrogen monoxide doesn't do it. Is that N2O or NO.

@DrBob222 what are you talking about which one is it?

To determine the number of moles of nitrogen monoxide gas (N2) in a 1.49 L container at standard temperature and pressure (STP), we can use the ideal gas law. The ideal gas law equation is expressed as:

PV = nRT

Where:
P = pressure (in atm)
V = volume (in L)
n = number of moles
R = gas constant (0.0821 L·atm/mol·K)
T = temperature (in Kelvin)

At STP, the temperature is 273.15 K and the pressure is 1 atm.

Let's calculate the number of moles, n:

n = PV / RT

Plugging in the given values:
P = 1 atm
V = 1.49 L
R = 0.0821 L·atm/mol·K
T = 273.15 K

n = (1 atm * 1.49 L) / (0.0821 L·atm/mol·K * 273.15 K)

Now, calculate the value of n using a calculator:

n ≈ 0.0687 mol

Therefore, the correct answer is approximately 0.0687 mol. None of the given options match this value.
