What is the pressure of a 15.0-L compressed gas tank that holds 17.8 mol of carbon dioxide gas at 375 K?

Question

Quizplus · Accepted Answer

To find the pressure of the gas, we can use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (0.0821 L·atm/(mol·K)), and T is the temperature in Kelvin. Rearranging the equation to solve for P gives us P = nRT/V. Plugging in the given values (n = 17.8 mol, R = 0.0821 L·atm/(mol·K), T = 375 K, and V = 15.0 L) gives us P = (17.8 mol)(0.0821 L·atm/(mol·K))(375 K) / (15.0 L) = 36.5 atm.
