When 10.0 g of potassium hydroxide (KOH) is dissolved in 100.0 g of water, the temperature rises from 25.18 °C to 47.53 °C. What is the heat of solution of KOH in units of joules/gram? The total mass of the solution is 110.0 g (100.0 g H2O + 10.0 g KOH = 110.0 g) and its specific heat capacity is 4.18 J/(g·K).

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
