Answer 1

The volume of a gas can be calculated using the Ideal Gas Law: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (8.31 J/mol·K), and T is the temperature in Kelvin.

First, we need to convert the temperature to Kelvin: T = -4.5°C + 273.15 = 268.65 K

Next, we can plug in the values and solve for V:
V = (nRT)/P = (1.25 moles * 8.31 J/mol·K * 268.65 K) / 1.20 atm = 245.84 L.

So, the volume of the gas is 245.84 liters
