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.
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
