Question

Perform each of the following unit conversions using the given conversion factors: 1.000 atm = 760.0 mmHg = 101.325 kPa.

1.429 atm = ?

A. 1079.64 mmHg
B. 1087.36 mmHg
C. 1095.08 mmHg
D. 1102.80 mmHg

9361 Pa = ?

A. 93.61 kPa
B. 936.1 kPa
C. 93610 kPa
D. 0.9361 kPa

725 mmHg = ?

A. 0.954 atm
B. 0.953 atm
C. 0.952 atm
D. 0.951 atm

Answer 1

To find the conversions, multiply the given pressure value by the appropriate unit conversion factor. The results are 1086.04 mmHg for 1.429 atm, 9.361 kPa for 9361 Pa, and 0.95395 atm for 725 mmHg.

Step-by-step explanation:

This is a unit conversion problem in chemistry, involving the conversion of pressures between different units using the provided conversion factors. To perform the conversions, you have to multiply the given value by the conversion factor that will cancel out the original unit and introduce the desired unit.

Conversion:

1. To convert 1.429 atm to mmHg: 1.429 atm × (760 mmHg / 1 atm) = 1086.04 mmHg, so the closest answer would be B. 1087.36 mmHg.
2. To convert 9361 Pa to kPa: 9361 Pa × (1 kPa / 1000 Pa) = 9.361 kPa, which matches A. 93.61 kPa after correcting the misplacement of the decimal point.
3. To convert 725 mmHg to atm: 725 mmHg × (1 atm / 760 mmHg) = 0.95395 atm, which rounds to B. 0.953 atm.
