A0.742 atm
B1.03 atm
C0.976 atm
D1.02 atm
Answer & Solution
Correct answer: C. 0.976 atm
1. The conversion factor is 1 atm = 760 torr.
2. Divide the reading by that factor: 742 torr / 760 torr per atm.
3. This gives 0.976 atm.
4. Because 742 torr is below 760 torr, the answer must be under 1 atm, which rules out 1.02 atm and 1.03 atm at a glance.
