Answer:
Avogrado's number
Explanation:
It's unniversal measure of moles
This is an application of osmotic pressure which is one of the colligative properties of substances. The formula of osmotic pressure is expressed as P = MRT where M is molarity , R is the gas constant and T is temperature. When M is equal to a total of 0.305 M and T is equal to 298 K , P should be equal to 7.46 atm
Answer:
D. Solution A has more concentrated acid than solution B and acid in solution A is also a weaker acid than that in solution B.
Explanation:
As it has been said in the question that the volume to reach the equivalence point of the solution A is twice the volume of solution B, this is because the acid in the solution A is more concentrated than B that's why more NaOH was required to reach to the equivalence point.
Since the pH at the equivalence point was greater for solution A that means the acid in solution A was a weak acid that's why the pH raised more as the NaOH was added to the solution.
I believe it is H--CH3, as the difference in electronegativity is larger
