Question 4 : 770 mm Hg = how many pascals

Conversion from mm Hg to atm :

  • 760 mm Hg = 1 atm

  • 1 mm Hg = 1 / 760 atm

  • 770 mm Hg = (1 / 760) × 770 atm

  • 770 mm Hg = 1.013 atm

Conversion from atm to kPa :

  • 1 atm = 1.013 × 10² kPa

  • 1.013 atm = 1.013 × 1.013 × 10² kPa

  • 1.013 atm = 1.026 × 10² kPa

Conversion of kPa to Pa :

  • 1.013 atm = 1.026 × 10² × 10³ Pa

  • 1.013 atm = 1.026 × 10⁵ pascals

hence, 770 mm Hg = 1.026 × 10⁵ Pa
