Question

You are planning an experiment that requires 0.0900 mol of nitrogen monoxide gas (NO). What volume would you need at STP? Answer in units of L.​

Answer 1

Answer: The volume needed at STP is 2.016 L

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
`6.023* 10^(23)` of particles.

To calculate the moles, we use the equation:

`\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar volume}}`

`0.0900mol=(x)/(22.4L/mol)`

`x=0.0900mol* 22.4L/mol=2.016L`

Thus the volume needed at STP is 2.016 L
