An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The question asks for the normal range of serum creatinine in men.
The normal range is generally considered to be 0.6 − 1.2 m g / d L .
Comparing with the given options, the correct range is 0.6 − 1.2 m g / d L .
The final answer is 0.6 − 1.2 m g / d L .
Explanation
Understanding the Question The question asks for the normal range of serum creatinine in men from the given options. We need to identify the correct range from the provided choices.
Identifying the Correct Range The normal range for serum creatinine in men is generally considered to be between 0.6 to 1.2 mg/dL. Comparing this with the given options, we can identify the correct range.
Final Answer The correct option is 0.6 − 1.2 m g / d L .
Examples
Understanding normal ranges for medical tests like serum creatinine is crucial in healthcare. For instance, if a doctor orders a creatinine test for a male patient and the result comes back as 1.5 mg/dL, it could indicate a potential kidney issue. Knowing the normal range helps the doctor interpret the results accurately and decide on the next steps, such as further testing or treatment. This knowledge is also useful in monitoring patients with chronic kidney disease to ensure their creatinine levels stay within an acceptable range. The normal range of serum creatinine in men is 0.6 − 1.2 m g / d L .
The number of electrons that flow through an electric device delivering a current of 15.0 A for 30 seconds is approximately 2.81 x 10^21 electrons. This was calculated using the relationship between current, charge, and time. We found the charge delivered in that time and then calculated the number of electrons using the charge of a single electron.
