Question

Which of the following shows the correct setup in converting 234 kilopascals to torr?
234 kPa times 1.01325 Torr over 760.0 kPa
234 kPa times 760.0 Torr over 101.325 kPa
101.325 kPa times 760.0 Torr over 1.01325 kPa
234 kPa times 760.0 Torr

Answer 1

Look to see if the units cancel out, you can treat units like numbers when dividing for example,

1 kg*1000g/1kg = 1000g

the kg cancels out in the fraction and you are left with the unit grams, if you wanted to convert back to grams you would flip the fraction to cancel out grams

1000g*1kg/1000g = 1kg

grams cancel out

its as easy as setting up a ratio and then multiplying it by the number you are converting. That is why I used the ratio,

1000g/1kg to convert kg to grams
and
1kg/1000g to convert to grams to kg

knowing

1kg = 1000g
