Chemistry Question 13

Question

Using the Ideal Gas Law and the given measurements, solve for the unknown variable.

How many moles of Rn are in a 63.353 L container at 5.8102 atm and 527 K?

Answer 1

The general Ideal Gas Law formula is

PV = nRT

For this scenario you want to solve for the number of moles (n) and then plug in the values that you know from the information given in the question

n = PV / RT

n = (5.8102 x 63.353) / (0.08206*527) = 8.5117 mol

meaning that there are 8.5117 moles of Radon (Rn) in the container
