Interpretation:
The diameter of the spherical hydrogen filled balloon needs to be calculated, if the balloon and balloonist together weigh 168 kg and if the temperature is 22 0C and pressure is 758 mm Hg.
Concept introduction:
According to the
When gases are placed at two different conditions, then to determine the changed variable, combined gas law is used. Below is the formula of combined gas law:
Here,
- P1 and P2 are the pressure of gases
- V1 and V2 and volume of gases
- n1 and n2 number of moles
- T1 and T2 are the temperature of gases
Formula to calculate the density is:
Here d is the density, MM is the molar mass of gas, P is pressure, R is gas constant and T is temperature.
And the formula to calculate the volume of sphere =

- perform stoichiometric ca1cu1uions for reactions involving gases as reactants or products.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_forwardA sample of a breathing mixture for divers contained 34.3% helium, He; 51.7% nitrogen, N2; and 14.0% oxygen, O2 (by mass). What is the density of this mixture at 22C and 775 mmHg?arrow_forward
- Helium-filled balloons rise in the air because the density of helium is less than the density of air. (a) If air has an average molar mass of 29.0 g/mol, what is the density of air at 25C and 770 mm Hg? (b) What is the density of helium at the same temperature and pressure? (c) Would a balloon filled with carbon dioxide at the same temperature and pressure rise?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_forwardGiven that a sample of air is made up of nitrogen, oxygen, and argon in the mole fractions 0.78 N2, 0.21 O2, and 0.010 Ar, what is the density of air at standard temperature and pressure?arrow_forward
- 109 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_forward97 Homes in rural areas where natural gas service is not available often rely on propane to fuel kitchen ranges. The propane is stored as a liquid, and the gas to be burned is produced as the liquid evaporates. Suppose an architect has hired you to consult on the choice of a propane tank for such a new home. The propane gas consumed in 1.0 hour by a typical range burner at high power would occupy roughly 165 L at 25°C and 1.0 atm, and the range chosen by the client will have six burners. If the tank under consideration holds 500.0 gallons of liquid propane, what is the minimum number of hours it would take for the range to consume an entire tankful of propane? The density of liquid propane is 0.5077 kg/L.arrow_forwardWhile resting, the average 70-kg human male consumes 14 L of pure O2 per hour at 25 C and 100 kPa. How many moles of 02 are consumed by a 70 kg man while resting for 1.0 h?arrow_forward
- A mixture of chromium and zinc weighing 0.362 g was reacted with an excess of hydrochloric acid. After all the metals in the mixture reacted, 225 mL dry of hydrogen gas was collected at 27C and 750. torr. Determine the mass percent of Zn in the metal sample. [Zinc reacts with hydrochloric acid to produce zinc chloride and hydrogen gas; chromium reacts with hydrochloric acid to produce chromium(III) chloride and hydrogen gas.]arrow_forwardFor a spacecraft or a molecule to leave the moon, it must reach the escape velocity (speed) of the moon, which is 2.37 km/s. The average daytime temperature of the moons surface is 365 K. What is the rms speed (in m/s) of a hydrogen molecule at this temperature? How does this compare with the escape velocity?arrow_forward
