Calculate the moles of hydrogen `(H_(2))` present in a 500 mL sample of hydrogen gas at a pressure of 1 bar and `27^(@)C`.

Text Solution

AI Generated Solution

To calculate the moles of hydrogen gas `(H₂)` present in a 500 mL sample at a pressure of 1 bar and a temperature of 27°C, we will use the Ideal Gas Law, which is given by the equation: \[ PV = nRT \] Where: - \( P \) = pressure in bar - \( V \) = volume in liters - \( n \) = number of moles ...
