AI Thread Summary
The discussion focuses on calculating the volume occupied by 1 g mole of an ideal gas at 356.2K and 1 atm using the ideal gas law. The user initially miscalculated the volume, arriving at 2.92 x 10^-5 m³, but later corrected their mistake to find the correct volume of 29.236 L. Key constants used include Avogadro’s number and the Boltzmann constant. The calculations involve converting units and applying the ideal gas equation accurately. The final result confirms the volume of the gas under the specified conditions.

Homework Statement


A gas obeys the ideal-gas equation of state PV = NkT , where N = nNA is the number of molecules in the volume V at pressure P and temperature T and n is the number of g moles of the gas.
Calculate the volume (in L) occupied by 1 g mole of the gas at atmospheric pressure and a temperature of 356.2K

1 atm = 1.013 × 105 N/m2
Avogadro’s constant is 6.02214 × 1023
k = 1.38065 × 10-23 Nm/K.

Homework Equations



P V = N k T
= n NA * k T

The Attempt at a Solution


I tried working it, but the answer I come up with is wrong. Can someone point me in the right direction?

(1.013 x 105 Nm/K)( V ) = (1 x 10-3 kg)(1.38065x10-23 Nm/K)(6.02214 x1023)(356.2 K)

V = 2.92 x10-5 m3
= 2.92 x10-2 L

Well, I reworked the problem and found my mistake. I got this to work out right:
(1.013x10^5)(V)=(356.2)(6.02214x10^23)(1.38065x10^-23)
V=.029236 m^3
V=29.236 L
 
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 '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...
