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.

- 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_forwardA cylinder with a movable piston records a volume of 12.6 L when 3.0 mol of oxygen is added. The gas in the cylinder has a pressure of 5.83 atm. The cylinder develops a leak and the volume of the gas is now recorded to be 12.1 L nt the same pressure. How many moles of oxygen are lost?arrow_forwardConsider the following sketch. Each square in bulb A represents a mole of atoms X. Each circle in bulb B represents a mole of atoms Y. The bulbs have the same volume, and the temperature is kept constant. When the valve is opened, atoms of X react with atoms of Y according to the following equation: 2X(g)+Y(g)X2Y(g)The gaseous product is represented as and each represents one mole of product. (a) IfP A=2.0 atm, what is P8 before the valve is opened and the reaction is allowed to occur? What is P A+P B? (b) Redraw the sketch to represent what happens after the valve is opened. (c) What is PA? What is PB? What is P A+P B? Compare your answer with the answer in part (a).arrow_forward
- A halothane-oxygen mixture (C2HBrCIF3 + O2) can be used as an anesthetic. A tank containing such a mixture has the following partial pressures: P (halothane) = 170 mm Hg and P (O2) = 570 mm Hg. (a) What is the ratio of the number of moles of halothane to the number of moles of O2? (b) If the tank contains 160 g of O2, what mass of C2HBrCIF3 is present?arrow_forwardA person exhales about 5.8 102 L of carbon dioxide per day (at STP). The carbon dioxide exhaled by an astronaut is absorbed from the air of a space capsule by reaction with lithium hydroxide, LiOH. 2LiOH(s)+CO2(g)Li2CO3(s)+H2O(l) How many grams of lithium hydroxide are required per astronaut per day?arrow_forward
