Question

angela has an unknown quantity of gas held at a temperature of 2300 K in a container with a volume of 19 L and a pressure of 6.00 atm. How many moles of gas does angela have? a. what equation will you use? b. show all your work.

Answer 1

The equation you should use is the ideal gas law: PV=nRT

Where P= pressure in atm (atmospheres)
V= Volume in liters
n= Moles of particles
R= Gas constant=0.08206
T= Temperature in Kelvin (degrees Celsius+273)

We are given everything except the amount of moles of the gas, but we want to find it. We can do this by plugging in everything we know into the equation and solving for n. Which would look like this:

(6)(19)=n(0.08206)(2300)

114=n(188.738)

Now divide both sides by 188.738 to get n by itself

0.7629=n

This means that there are 0.7629 moles of the gas!

If you have any additional questions feel free to ask!
Hope this helps!! :))
