Question

If I have an unknown quantity of gas at a pressure of 2.9 atm, a volume of 7.4 liters, and a temperature of 58.6 oC, how many moles of gas do I have?

Answer 1

Answer: 0.788 mol

Explanation:

To solve, you use the ideal gas law equation which is PV=nRT

P= pressure (atm)

V= volume (L)

n= mol

R= 0.0821 atm*L/mol*K (constant)

T= temperature (K)

First you have to turn the temperature into K by adding 273. After that, you rearrange to equation into n=PV/RT, plug in your values, and solve.
