PROBLEM 25P

Perform each conversion.

(a) 2.3 atm to torr

(b) 4.7 × 10−2 atm to millimeters of mercury

(c) 24.8 psi to millimeters of mercury

(d) 32.84 in. Hg to tor

Solution 25P

Here, we are going to convert the unit.

(a) 2.3 atm to torr

We know, 1 atm =760 torr

Conversion factor =

Thus, 2.3 atm = 2.3 atm x = 1748 torr.

Therefore, 2.3 atm = 1748 torr.

(b) 4.7 × 10−2 atm to millimeters of mercury

1 atm = 760 mmHg

Conversion factor =

Thus, 4.7 × 10−2 atm = 4.7 × 10−2 atm x = 35.72 mm Hg

Therefore, 4.7 × 10−2 atm = 35.72 mm Hg

(c) 24.8 psi to millimeters of mercury

We know,

1 atm = 14.695975 psi

1 atm = 760 mmHg

Conversion factor = ,

Thus. 24.8 psi = 24.8 psi x x = 1282.528 mm Hg

Therefore, 24.8 psi = 1282.528 mm Hg

(d) 32.84 in. Hg to torr

We know

1 inHg = 25.399904 mmHg

1 mmHg = 1 torr

Conversion factor = ,

Thus, 32.84 in. Hg x x = 834.13 torr
