HELPPPP!!! SHOW WORK

On the day this exercise was written, atmospheric pressure was 745.8 mm Hg. Calculate the pressure in units of atmospheres, cm Hg, lbs./in2, and torr

Answer 1

1) 0.98 atm

2) 74.58 cmHg

3) 14.47 lbs./in²

4) 745.8 torrs

Step-by-step explanation:

We are given the atmospheric pressure as 745.8 mmHg

1) Converting mmHg to atmospheres(atm), we divide the pressure by 760.

P = 745.8/760

P = 0.98 atm

2) Converting mmHg to cmHg, we multiply the pressure by 0.1;

P = 745.8 × 0.1

P = 74.58 cmHg

3) Converting mmHg to lbs./in², we divide the pressure by 51.75;

P = 748.5/51.715

P = 14.47 lbs./in²

4) Converting mmHg to torrs, we multiply the pressure by 1;

P = 745.8 × 1

P = 745.8 torrs
