Question: convert 22.63 miles of oxygen to volume<br><br> very urgent
Stels [109]

Answer:

506.912 L

Explanation:

From the question given above, the following data were obtained:

Number of mole of O₂ = 22.63 moles

Volume of O₂ =?

Recall:

1 mole of a gas occupy 22.4 L at STP.

With the above information, we obtained the volume occupied by 22.63 moles of O₂ as follow:

1 mole of O₂ occupied 22.4 L at STP.

Therefore, 22.63 moles of O₂ will occupy = 22.63 × 22.4 = 506.912 L at STP.

Thus, 22.63 moles of O₂ is equivalent to 506.912 L.

Give four examples of properties of nonmetals that are exactly the opposite of the properties of metals
Ugo [173]
The properties of nonmetals- nonductile(cannot be turned into wire), dull color, high solubility, poor conductors, brittle(difficult to break) and have a wide range of colors. Compared to the properties of a metal- polished color, conducters of heat and electricity, cannot be dissolved, malleable(can bend). Would you like me to use certain elements to show this?
