Question
Yellow- 8, Purple-4, Green-5, brown-3
Be sure to answer all parts.
The circle at right represents a portion of a mixture of four gases: Gas A (purple), Gas B (brown), Gas C (green), and Gas D2 (orange).
(since i cant post the picture, ill expain it)
(a) Which gas has the highest partial pressure?
Gas A has the highest partial pressure
Gas B has the highest partial pressure
Gas C has the highest partial pressure
Gas D2 has the highest partial pressure
(b) Which gas has the lowest partial pressure?
Gas A has the lowest partial pressure
Gas B has the lowest partial pressure
Gas C has the lowest partial pressure
Gas D2 has the lowest partial pressure
(c) If the total pressure is 0.890 atm, what is the partial pressure of D2?
Explanation / Answer
a)
the gas with highest number of molecule will have highest partial pressure
yellow has highest molecule which is gas D2
Answer: Gas D2 has the highest partial pressure
b)
the gas with lowest number of molecule will have lowest partial pressure
brown has lowest molecule which is gas B
Answer: Gas B has the lowest partial pressure
c)
partial pressure of D = number of D * total pressure / total molecule
= 8*0.890 atm / (8+4+5+3)
= 0.356 atm
Answer: 0.356 atm
