What he means is:

When 5g of NaOH is added to 100g of water, the temp. rises from 25 to 37.5 degrees. Calculate the molar heat of solution, delta H

NaOH-->Na + OH

Assume that the specific heat of water is 4.18JgK and that of theNaOH solution is the same.

When a question mark is added to the end of a sentence, it becomes a question. When a sentence is punctuated properly, it becomes legible. When someone else does your boring homework for you, you learn nothing. Incidentally, temperature is measured in Fahrenheit, Centigrade, and Kelvin. Most people learn that early on.
