Question

If I have an unknown quantity of gas held at a temperature of 1195 K in a container with a volume of 25 liters and a pressure of 1,000 atm, how many moles of gas do I have?

Answer 1

I think you use PV= nRt.

So P=1000
V=25
We are trying to find the moles so n is blank.
R=0.08206
T=1195

This means that your equation is:

(1000)(25) = (n)(0.08206)(1195)

So you are gonna divide each side by (0.08206)(1195) because you are trying to get the moles by itself.

(0.08206)(1195) is gonna cancel each other out, so your new equation is going to be:

(1000)(25)/0.08206/1195 = n

Put that into your calculator and you get:

n= 254.941532

or 254.94moles

If i’m wrong please correct me.
