✏️IDEAL GAS EQUATION

The problem asks to solve for the pressure of the gas inside the tank. First, we need to identify the quantities to be used. These are

P = pressure

V = volume

n = number of moles

R = universal gas constant = 0.082057 L • atm/K • mol

T = absolute temperature

m = mass

MW = molecular weight

Second, we need to identify the given values. These are

V = 25.0 L

T = 25°C + 273.15 = 298.15 K

m = 11.0 kg = 1.10 × 10⁴ g

Third, we need to find the molecular weight of gas. Since the given gas is butane, the molecular weight is

MW = (12.01 g/mol × 4) + (1.008 g/mol × 10)

MW = 58.12 g/mol

Fourth, we need to find the number of moles of gas. The number of moles of butane gas is

n = 189.26 mol

Finally, we can now solve for the pressure of the gas. Therefore, the pressure of the gas is
