Question
There are four 250 mL glass bulbs at 25 °C and 0.50 bar. One bulb contains CO2, one contains H2, one contains Ar, and one contains SF6. What can be said about the number of molecules of gas in the four bulbs?
a. The number of molecules in each of the four bulbs is the same.
b. The number of molecules in the bulb containing Ar is the largest.
c. The number of molecules in the bulbs containing Ar and H2 is larger than the number of molecules in the bulbs containing CO2 and SF6.
d. The number of molecules in the bulb containing SF6 is the largest.
Explanation / Answer
Since pressure, volume and Temperature is same for all, the number of moles will be same for all.
Since number of moles if same, number of molecules will be same
Because number of molecules = number of moles * Avogadro’s number
