How do I perform the following conversions of pressure units: 168 torr = What?
168 torr = what what? mm Hg, atmosphere, pascals, what?
Your question is the same as me asking you the following:
How do I perform the following conversion of dollar units to: 100 dollars = what?
To convert pressure units from torr to another unit, such as atmospheres (atm), you need to use a conversion factor.
One conversion factor to convert torr to atm is:
1 atm = 760 torr
To perform the conversion, you can use the following steps:
Step 1: Write down the given value and the conversion factor in a fraction:
168 torr / 1
Step 2: Multiply the given value by the conversion factor, ensuring the units cancel out correctly:
168 torr * (1 atm / 760 torr)
Note that torr will cancel out, leaving you with the desired unit of atm:
168 / 760 atm
Step 3: Simplify the fraction if needed:
The numerator (168) and denominator (760) do not share any common factors other than 1. So the simplified answer is:
168 / 760 atm
Step 4: Evaluate the fraction using a calculator to obtain the decimal value:
168 / 760 ≈ 0.2211
Therefore, 168 torr is approximately equal to 0.2211 atm.
