Question

Use the Ideal Gal Law to calculate the following problem. How many moles of gas are contained in a 4.2 L container at 2.7 atm and 305 K?

Answer 1

0.453 moles

Step-by-step explanation:

The Ideal Gas Law equation looks like this:

PV = nRT

In this formula,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = Ideal Gas Constant (0.08206 atm*L/mol*K)

-----> T = temperature (K)

To find the amount of moles of gas, you can plug the given values into the equation and then simplify.

P = 2.7 atm R = 0.08206 atm*L/mol*K

V = 4.2 L T = 305 K

n = ? moles

PV = nRT

(2.7 atm)(4.2 L) = n(0.08206 atm*L/mol*K)(305 K)

11.34 = n(25.0283)

0.453 = n
