Question

One component of smog is nitrogen

monoxide, NO. A car produces about 8 g of
this gas per day. What is the volume at STP?

Answer 1

V = 5.97 L

Step-by-step explanation:

Hello!

In this case, according to the ideal gas law:

`PV=nRT`

We would need to solve for V as we know the temperature and pressure as the gas it at STP conditions (273 K and 1 atm respectively):

`V=(nRT)/(P)`

Next, we compute the moles in 8 g of NO, given its molar mass of 30.01 g/mol:

`n=(8g)/(30.01g/mol)=0.267mol`

Therefore, we obtain the following volume:

`V=(0.267mol*0.08206(atm*L)/(mol*K)*273K)/(1atm)\\\\V=5.97 L`

Best regards!
