Concept explainers
(a)
Interpretation:
If the pressure of a sample of gas is held constant, its volume, V, is directly proportional to the absolute temperature of the gas, T. An equation for the proportionality between V and T, in which b is the proportionality constant is to be stated.
Concept introduction:
Generally, proportionality is stated as two varying quantities having multiplicative connection with proportionality constant. When either of their ratio or their product yields a value, this value is called proportionality constant or coefficient of proportionality. The variable of y is related with another variable x via a proportionality constant c as
(b)
Interpretation:
For 48.0 grams of O2 gas at a pressure of 0.373 atmospheres, V is observed to be 93.4 L when T is 283 K. The value and units of the proportionality constant, b is to be calculated.
Concept introduction:
Generally, proportionality is stated as two varying quantities having multiplicative connection with proportionality constant. When either of their ratio or their product yields a value, this value is called proportionality constant or coefficient of proportionality. The variable of y is related with another variable x via a proportionality constant c as y = cx. In other words, the value of proportionality constant c is given by y/x.
(c)
Interpretation:
The volume will this gas sample occupy at a temperature of 375 K is to be stated.

- What is the value of FT for a sample of gas whose volume is 2.97 L and pressure is 0.0553 atm? What could the volume of the gas be if the pressure were increased to 1.00 atm?arrow_forwardA mixture contained calcium carbonate, CaCO3, and magnesium carbonate, MgCO3. A sample of this mixture weighing 7.85 g was reacted with excess hydrochloric acid. The reactions are CaCO3(g)+2HCL(aq)CaCl2(aq)+H2O(I)+CO2(g)MgCO3(s)+2HCL(aq)MgCl2(aq)+H2O(I)+CO2(g) If the sample reacted completely and produced 1.94 L of carbon dioxide, CO2, at 25C and 785 mmHg, what were the percentages of CaCO3 and MgCO3 in the mixture?arrow_forward109 An ore sample with a mass of 670 kg contains 27.7% magnesium carbonate, MgCO3. If all of the magnesium carbonate in this ore sample is decomposed to form carbon dioxide, describe how to determine what volume of CO2 is evolved during the process. What would have to be measured to predict the needed volume in advance?arrow_forward

(b) Does your answer depend on knowing what gas it is?arrow_forwardA sample of natural gas is 85.2% methane, CH4, and 14.8% ethane, C2H6, by mass. What is the density of this mixture at 18C and 771 mmHg?arrow_forwardThe compression ratio in an automobile engine is the ratio of the gas pressure at the end of the compression stroke to the pressure in the beginning. Assume that compression occurs at constant temperature. The total volume of the cylinder in an automobile is 350 cm3, and the displacement the reduction in volume during the compression stroke is 309 cm3. What is the compression ratio in that engine?arrow_forward

To do this, calculate a value of the molar mass at each of the given pressures from the ideal gas law (we will call this the apparent molar mass at this pressure). On a graph show the apparent molar mass versus the pressure and extrapolate to find the molar mass at zero pressure. Because the ideal gas law is most accurate at low pressures, this extrapolation will give an accurate value for the molar mass. What is the accurate molar mass?arrow_forward
