2. Convert the following barometric readings to atmospheres (atm):
a) 1.890 mm Hg
b) 306,000 Pa
c) 100 psi
d) 5000 mb

Please help 15 points!

(a) 693.12 torr

(b) 68.5 kilopascals

(c) 0.862 atmosphere

(d) 1.306 atmospheres

(e) 36.74 psi

Explanation:

(a) 0.912 atm = 0.912 atm × 760 torr/1 atm = 693.12 torr

(b) 0.685 bar = 0.685 bar × 100 kPa/1 bar = 68.5 kPa

(c) 655 mmHg = 655 mmHg × 1 atm/760 mmHg = 0.862 atm

(d) 1.323×10^5 Pa = 1.323×10^5 Pa × 1 atm/1.01325×10^5 Pa = 1.306 atm

(e) 2.50 atm = 2.50 atm × 14.696 psi/1 atm = 36.74 psi

i believe that it is a exoplanet
