Given :
Concentration of hydrogen ions, .
To Find :
The pH of a solution.
Solution :
We know, pH of a solution is given by :
Therefore, the pH of the solution is 3 .
Liquids than have the next smallest density because the particles of a liquid are closer together but not as tightly bound together as a solid, or loosely structured as a gas. Solids are the most dense. ... For each element, pure substance or mixture the gas state will always have a lower density.
Answer:
Explanation:
Heat of combustion is the amount of heat released when 1 mole of the compound is completely burnt in the presence of oxygen.
To calculate the moles, we use the equation:
Thus of sucrose releases = 916.6 J of heat
1 mole of sucrose releases = of heat
Thus ∆H value for the combustion reaction is
.513mol x (102g/1mol)
Essentially, this is .513 x 102
Which equals: 52.326
But because you can only have 3 significant figures, your answer is:
52.3 grams
I hope this Helps!
