A pressure of 745 mm hg equals select one:

a. 745 torr.
b. 1 torr.
c. 1 pascal.
d. 745 pascal.

Answered by admin @ 05/11/2021

As we know that,

1 mm Hg = 1 torr
So,
745 mm Hg = X

X = (745 mm Hg × 1 torr) ÷ 1 mm Hg

X = 745 torr

Also,
1 mm Hg = 133.325 Pa
So,
745 mm Hg = X

X = (745 mm Hg × 133.325 Pa) ÷ 1 mm Hg

X = 99327 Pa

Result:
Option-A (745 torr) is the correct answer.
