Question

Suppose you want to measure the partition coefficient, K. of a protein in an aqueous two-phase system. You know the "true" value of K to be 34. You attempt to develop u new method of measuring the value of K for your protein. The experimental results are as follows: Classify the accuracy and precision of your experimental protocol. Your experimental protocol is accurate, and is precise. Your experimental protocol is accurate, and is not precise. Your experimental protocol is not accurate, and is precise. Your experimental protocol is not accurate, and is not precise. Which of the following atoms has the largest diameter? O (oxygen union) O (neutral oxygen) O^+ (oxygen cation) All of these atoms have the same diameter. In the future, europium (Eu) may be used in "quantum computing." enabling much faster calculations than in traditional binary computers. The exact masses of Eu-151 and Eu-153 are 150.919660 and 152, 921243 amu, respectively. Calculate the percent natural abundance of Eu-153, given that the exact mass of the element europium is 151.964 amu 47.8% 50.1% 52 2% 5 .1%

Explanation / Answer

5. All values are exact. hence they are accurate. but they largely vary from one another. Hence they are not precise

6. a has largest diameter

O+ has increased charg density hence less diameter.

7.

a

x= abundance of Eu-153 (percentage)
(mass of Eu-151) (1 - x ) + (mass of Eu-153) ( x ) = 151.964

Calculate for x. x = .478
