if i have 7.7 moles of gas at a volume of 22.3 L, what would be the new volume be if the amount if gas is decreased to 5.0 moles
If we assume the gas follows the ideal gas law, we can use the formula:
PV = nRT
Where:
P = pressure (assume constant)
V = volume
n = moles of gas
R = gas constant
T = temperature (assume constant)
Since the pressure and temperature are assumed to be constant, we can simplify the equation to:
V1 * n1 = V2 * n2
Where:
V1 = initial volume
n1 = initial moles of gas
V2 = final volume
n2 = final moles of gas
Plugging in the values:
(22.3 L)(7.7 mol) = V2(5.0 mol)
V2 = (22.3 L * 7.7 mol) / 5.0 mol
V2 = 34.31 L
Therefore, the new volume would be 34.31 L if the amount of gas is decreased to 5.0 moles.
