Answer:
the percent error expected from each of theses person's body:
in homes:
% E = 0.14267 %
in doctor's office:
% E = 0.257 %
Explanation:
- ° C = ( ° F - 32 ) * (5/9)
- % E = ( | true - exp | / true ) * 100
- body temp = 38.9 ° C = 102.02 ° F
thermometer used in homes:
⇒ T = 102.02 ° F +/- 0.1 ° F = 102.12 ° F ∧ 101,92 ° F
⇒ T = 102.12 ° F = 38.9555 ° C
⇒ % E = ( | 38.9 - 38.9555 | ) / 38.9 ) * 100 = 0.14267 %
in the doctor's oficce:
⇒ T = 38.9 ° C +/- 0.1 ° C = 39 ° C ∧ 38.8 ° C
⇒ % E = (( | 39 - 38.9 | ) / 38.9 ) * 100 = 0.257 %
Solute s has a distribution constant of 5. 0 between water (phase 1) and hexane (phase 2), then the concentration of solute s in hexane if [s]water is 0. 011 m is 0.055m.
<h3>What is partition Coefficent?
</h3>
It is defined as the ratio of the concentration of solute in two immiscible ( or slightly miscible liquid) in two solids, when they are in equilibrium across the interface between them.
<h3>What is concentration?</h3>
It is defined as the ratio of number of moles of compound to the volume of compound.
Solute S has a partition coefficient of 5 between water and hexane
Partition coefficient Kd = 5.0
Now we calculate the concentration of S in hexane
[hexane]/[water] = Kd
[Hexane]= 5.0 × (water)
[Hexane] = 5 × (0. 011)
[Hexane] = 0.055 m
Thus, we found that the concentration of solute of hexane if water is 0.011m is 0.055m.
