Question

Answer the following question:Reminder R= .0821. If you have a gas at 6 Atm and 4 L, how many moles are present if the temp is 300 K?

Answer 1

0.975609756 mol

Step-by-step explanation

Given:

Pressure, P = 6 atm

Volume, V = 4 L

Temperature, T = 300 K

Molar gas constant, R = 0.082

What to find:

The moles, n present.

Step-by-step solution:

The mole, n present can be calculated using the ideal gas equation, PV = nRT

6 x 4 = n x 0.082 x 300

24 = 24.6n

Diivide both sides by 24.6

24/24.6 = 24.6n/24.6

n = 0.975609756 mol

Hence, the moles that are present = 0.975609756 mol
