A pressure of 745 mm hg equals select one:

a. 745 torr.

b. 1 torr.

c. 1 pascal.

d. 745 pascal.

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.
