Final answer:
To find the equivalent pressure of 0.905 atm in units of mm Hg, you multiply 0.905 atm by 760 mmHg/atm to get 687.80 mm Hg.
Step-by-step explanation:
A pressure of 0.905 atm is equivalent to 691.9 mmHg. To convert from atmospheres to mmHg, we use the conversion factor 1 atm = 760 mmHg. Therefore, we can multiply 0.905 atm by 760 mmHg/atm to get the equivalent pressure in mmHg. This gives us 0.905 atm x 760 mmHg/atm = 691.9 mmHg.
To convert pressure from atm to mm Hg, we utilize the equivalence that 1 atm is equal to 760 mmHg. Given the pressure of 0.905 atm, we can calculate the equivalent pressure in mmHg by multiplying 0.905 atm by 760 mmHg/atm:
0.905 atm × 760 mmHg/atm = 687.80 mm Hg
This calculation allows us to express the pressure originally in atmospheres (atm) into millimeters of mercury (mm Hg), which is a common unit in measuring pressure. In conclusion, 0.905 atm is equivalent to 687.80 mm Hg.
