Answer:
As you noticed, the percent-error formula needs you to use a value in the ... The actual absolute zero is 275C below my coldest recorded value. ... The only way your calculations makes sense is you're trying to calculate how ... Next, I'll interpret "I found that AZ is at -258°C" as "I calculated AZ to be 260 degrees below 2°C".

Answer:
0.0005mol/kg
Explanation:
Molality = mole of solute/mass of solvent (kg)
From the question, we obtained the following data:
Mole of solute = 0.05mole
Mass of solvent = 100kg
Molality = 0.05/100
Molality = 0.0005mol/kg
The molality of the solution is 0.0005mol/kg

I just did the session question.
Answer:
A. 0.31 mol NaNO2
Explanation:
Buffer solutions are the solutions that resist changes in pH on addition of small amount of acid or base.
Buffer solutions usually contain the mixture of a weak acid and its salt, or a weak base and its salt.
Among the options listed in the question, only NaNO2 is the salt formed from the nitrous acid.
