(a)
Interpretation:
The determination of the molar mass of a gas at STP if its density is
(a)
Explanation of Solution
The molar mass of a gas at STP can be determined by using the value of its density. The density
The density of the gas is
Substitute the given values in the above expression:
The number of moles of the gas is equal to the ratio of the mass of the gas to the molar mass of that gas.
At STP, the number of moles of a gas is
(b)
Interpretation:
The determination of the molar mass of a gas at STP if its density is
(b)
Explanation of Solution
The density of the gas is
The number of moles of the gas is equal to the ratio of the mass of the gas to the molar mass of that gas.

Introduction to Chemistry
- Although we: generally think of combustion reactions as involving oxygen gas, other rapid oxidation reactions are also referred to as combustions. For example, if magnesium metal is placed into chlorine gas, a rapid oxidation takes place, and magnesium chloride is produced. msp;Mg(s)+Cl2(g)MgCl2(s) at Volume of chlorine gas, measured at STP, is required to react completely with 1.02gof magnesium?arrow_forwardBefore small batteries were available, carbide lamps were used for bicycle lights. Acetylene gas. C2H2, and solid calcium hydroxide were formed by the reaction of calcium carbide, CaC2. with water. The ignition of the acetylene gas provided the light. Currently, the same lamps are used by some cavers, and calcium carbide is used to produce acetylene for carbide cannons. (a) Outline the steps necessary to answer the following question: What volume of C2H2 at 1.005 atm and 12.2 C is formed by the reaction of 15.48 g of CaC2 with water? (b) Answer the question.arrow_forwardA gas effuses through an opening one-fifth as fast as helium gas effuses through the same opening. (a) Is the gas heavier than helium? (b) What is the molar mass of the gas?arrow_forward
- 5.18 When helium escapes from a balloon, the balloon’s volume decreases. Based on your intuition about stretching rubber, explain how this observation is consistent with the gas law.arrow_forwardEthanol, C2H5OH, is produced industrially from ethylene, C2H4, by the following sequence of reactions: 3C2H4+2H2SO4C2H5HSO4+( C 2 H 5)2SO4C2H5HSO4+( C 2 H 5)2SO4+3H2O3C2H5OH+2H2SO4 What volume of ethylene at STP is required to produce 1.000 metric ton (1000 kg) of ethanol if the overall yield of ethanol is 90.1%?arrow_forwardA 275-mL sample of CO gas is collected over water at 31C and 755 mmHg. If the temperature of the gas collection apparatus rises to 39C, what is the new volume of the sample? Assume that the barometric pressure does not change.arrow_forward
