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.​

Respuesta :

Answer:  The volume needed at STP is 2.016 L

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar volume}}[/tex]

[tex]0.0900mol=\frac{x}{22.4L/mol}[/tex]

[tex]x=0.0900mol\times 22.4L/mol=2.016L[/tex]

Thus the volume needed at STP is 2.016 L
