Moles

AI Thread Summary

To calculate the number of molecules in 23 moles of oxygen, use Avogadro's number, which states that 1 mole equals 6.022 x 10^23 molecules. Therefore, multiplying 23 moles by Avogadro's number results in approximately 1.384 x 10^24 molecules of oxygen. The user expresses confusion about this calculation compared to other mole conversions, indicating a need for clarification. Understanding the mole-to-molecule conversion is essential for accurate chemical calculations. The discussion emphasizes the importance of Avogadro's number in determining the number of molecules in a given amount of substance.

How many molecules are in 23 moles of oxygen?

I don't get it, I know how to do other kinds like How many moles are there in 25 grams of water? and How many grams are in 4.5 moles of Li20? but I don't get it.

THANK YOU in advance

I believe the conversion is:

1 mole=6.022 x 10^23 molecules

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Power of a thin lens in a medium is 1/fₘ or μₘ/fₘ ?'

Here is what I tried This question was actually asked in one of our engineering entrances. The answer was 1D. My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
