Do we use the ideal gas equation to solve this?

[Mallika Mathew]

What is the concentration of a gas at pressure 12.1 atm and temperature 23 degrees C?

[Dahlia Kirov 3A]

Yes, I believe so.

[Harry Forbeck 2A]

Yes, you can use PV=nRT to solve this

the question gives you P = 12.1 atm, and t = 23 C

then you want to rearrange the equation to solve for n/v = P/RT
n/v = 12.1 atm/0.08206 L*atm*K^-1*mol^-1 * 296 K
n/v = 0.50 M

you don't know the volume or moles individually, but the ratio is constant.

[Emily La 2B]

Yes, you would use the ideal gas law to solve this due to the known values of pressure, temperature, and the R constant.

[Jonathan_Yu_2C]

yes, you use pv=nrt to solve this

[Peter_Wisner_3F]

Yes, you can. If you have any three of pressure, volume, number of moles of gas, and temperature, you can use those values with the ideal gas equation to solve for the fourth value.

[Jenifer_Fonseca]

Yes we can!
P=1.2 atm
T=23 C
We know that R is a constant and we can find that in the equation sheet!
Then we know that we change the equation to ---->n/v = P/RT
