If an instant pot has an internal pressure of 191.0 kPa, temperature of 750.0 K and a volume of 6.5 L, how many moles of gas would be contained inside the instant pot?

0.200 mol.

Explanation:

Hello!

In this case, since this case is considered an ideal one (no intermolecular interactions), we can use the following equation:

Thus, since we know the pressure, temperature and volume, we are able to compute the moles shown below:

Best regards!

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
