(a)
Interpretation:
The number of moles of
Concept Introduction:
According to
For comparison, STP conditions are taken under consideration that is standard temperature and standard pressure.
Standard Temperature = 0oC (273 K)
Standard Pressure = 1 atm (760 mmHg)
At STP, one mole of any gas occupies a volume of 22.4 L and this volume of any gas is known as molar volume.
(b)
Interpretation:
The volume in litersoccupied by 0.420 mol of helium gas should be calculated by using molar volume.

Basic Chemistry
- A cylinder of a gas mixture used for calibration of blood gas analyzers in medical laboratories contains 5.0% CO2, 12.0% O2, and the remainder N2 at a total pressure of 146 atm. What is the partial pressure of each component of this gas? (The percentages given indicate the percent of the total pressure that is due to each component.)arrow_forwardHow would the graph in Figure 9.13 change if the number of moles of gas in the sample used to determine the curve were doubled?arrow_forward
