Answer
0.975609756 mol
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
