For this problem, we use the equation derived from Beer's Law as written below:
A = ∈LC,
where
A is the absorbance
∈ is the molar absorptivity
L is the path length of the cuvette
C is the concentration of the sample solution placed in the cuvette
To determine C, we have to know the rest of the parameters. Generally, the equation for C would be:
C = A/∈L = A/∈(1 cm)
C = A/∈
If you know the absorbance and the molar absorptivity in mol/L·cm, you can determine the value of C.
I think your answer choices are...
A. an educated guess
B. a statement of pure fact
C. a general principle based on an observable fact
D. a collection of data
Answer:
C. A general principle based on an observable fact
Explanation:
It can't be A as an educated guess is in scientific terms , a hypothesis.
It can't be B as that is a fact or a law
It can't be D as a collection of data is a data table.
Use the drop-down menus to select the correct answer for each statement. the correct answers are......
Current is the independent variable.
Voltage is the dependent variable.
This graph shows a(an) direct relationship.
A current of 0.04 A gives a voltage of 5.5 V.
A voltage of 2 V corresponds to a current of 0.014 A.
Answer:
null
Explanation:
the hypothesis is a typical statistical theory which suggest that no statistical relationship and significance exists in a set of a given single observed variable between two sets of the observed data and measured phenomena
This means that the air in that city has less than a third of water vapor it could contain under the same circumstances. Relative humidity is the ratio of water vapor that the air contains to the maximum amount it could carry at the same temperature. When the humidity is high the water vapor in the air is a lot and vice versa.
