The three chemicals listed below are all very weak acids because they all have a difficult time losing a hydrogen ion, H + . Upon losing this hydrogen ion, the central atom of each of these molecules takes on a negative charge. Holding onto this negative charge isn’t easy, especially when there are positively charged hydrogen ions, H + , floating about ready to combine with this negative charge. Review the concept of electronegativity in Section 15.6, and rank the acidity of these molecules in order from strongest to weakest: (a) ammonia, NH 3 ; (b) water, H 2 O; (c) methane, CH 4 .

Hello,
I am having an issue with figuring the following: For pH 9.5 I am getting 3.16 x 10 ^-10. Is this correct? Thank you
Solution X has a pH of 9.5, and solution Y has a pH of 7.6.?
What is [H3O+] in Solution X?
What is [H3O+] in Solution Y?
yeasts are able to produce high internal concentrations of glycerol to counteract the osmotic pressure of the surrounding media. suppose that a sample of yeast cells were placed in a 4% sodium chloride solution by weight.
The density of solution is at 25 C = 1.02 g/ml,
Molecular weight of solute = 58.44 g/mol,
i of glycerol = 1
R=0.08205 L-atm/mol-K
What is the weight of solute (in grams)?
What is the moles of solute?
What is the volume of the solution (in liters)?
What is the molarity of the solution?
What is the value of the temperature to be used to solve for the osmotic pressure of the solution?
What is the osmotic pressure of solution
At the same temperature, what will be the molar concentration of glycerol considering the computed osmotic pressure of the solution and the normal osmotic pressure inside a yeast cell of 7.3 atmospheres?
