Answer: (D) environmental chemistry
Explanation:
Answer:
1. 374.69 K
Explanation:
Hello,
In this case, pure water's boiling point is 373.15 K, thus by considering the boiling point increase equation:

Whereas i=2 since two ionic species are formed,actually, the experimental value is 2.42 so better work with it, thus:

Thus, the required boiling point is:
