Six grams of hydrogen gas at a temperature of 273 K isothoermally expanded to five times its initial volume and then isochorically heated so that the pressure in the final state becomes equal to that in the initial state. Find the total amount of heat absorbed by the gas during the entire process.

To solve the problem of finding the total amount of heat absorbed by the hydrogen gas during the entire process, we will break it down into two parts: the isothermal expansion and the isochoric heating. ### Step 1: Calculate the number of moles of hydrogen gas We start by converting the mass of hydrogen gas into moles. The molar mass of hydrogen (H₂) is approximately 2 g/mol. \[ \text{Number of moles} (n) = \frac{\text{mass}}{\text{molar mass}} = \frac{6 \text{ g}}{2 \text{ g/mol}} = 3 \text{ moles} \] ...
