Task:
The pressure is recorded as 738 mm Hg. Convert this measurement to atm
Solution:
To convert pressure in mm Hg to atm we should find the conversion factor first
1 atm = 760 mm Hg
P(atm) = P(mm Hg) ∙ f
f – conversion factor
The conversion factor is
f = 1/760
The pressure in atm is
P(atm) = 738 ∙ 1/760 = 0.971 atm
Answer: P (atm) = 0.971 atm
