What is the volume of .00831 mol of gas under ideal conditions if the pressure is 1.01 atm and the temperature is 25 degrees C?*

Approximately .

Explanation:

Convert the temperature of this gas to absolute temperature:

.

Let and represent the pressure and volume of this gas, respectively. Let represent the number of gas particles in this gas. Let represent the ideal gas constant. By the ideal gas law:

.

For this question:

Look up the ideal gas constant that takes as the unit for pressure:

.

This question is asking for , the volume of this gas. Rearrange the ideal gas equation and solve for :

.

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

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
