Simple Ideal Gas Law but i keep getting it wrong

AI Thread Summary
The discussion revolves around solving the ideal gas law equation PV=nRT to find the volume (V) given pressure (P), number of moles (n), gas constant (R), and temperature (T). The user initially calculated V as 0.027 L but received an error regarding significant figures. It was clarified that the conversion from cubic meters to liters was incorrectly done, as 1 m³ equals 1000 liters, not 1,000,000. After addressing the conversion issue, the user successfully arrived at the correct answer. Accurate unit conversion and attention to significant figures are crucial in solving gas law problems.

Homework Statement



P=1.5 atm; n=2 mols, R=8.314; T=250 K; V=?

Homework Equations


PV=nRT
i converted p into Pa and got 151987.5 Pa.


The Attempt at a Solution


I plugged in all of the numbers and got V=0.027 L but it keeps saying my answer is wrong. It says answer for 2 sig figs. I am not sure what I am doing wrong. Help please?

your answer is in m^{3}. You need to convert to liters. Hint:

<br /> 1 \, \mathrm{L} = 1 \, \mathrm{dm}^{3}<br />

I think something went wrong with your conversion from m3 to liters. There are 1000 liters in a m3 (not 1 000 000 -- that would be ml per m3). :wink:

[Edit: Oops, I see Dickfore beat me to the answer.]
 
Thanks I got it right!
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
