Answer to Problem 62GP
The decay time of one proton in the body is
Explanation of Solution
Given info:
Half-life of proton,
Known data:
Mass of water in human body,
Molar mass of water,
Formula used:
Number of molecules can be given as:
Here,
Decay time can be given as:
Here,
Calculation:
Firstly, calculate the number of water molecules as follows:
Now, the number of protons in a water molecule is 10. So, decay time can be given as:
Conclusion:
Thus, the decay time of one proton in the body is
