Answer:
V = 2.75 L
Explanation:
Given that,
Mass of liquid glycerol, m = 3470 g
The density of liquid glycerol, d = 1.26 g/cm³
We need to find the volume of liquid glycerol.
We know that,
Density=mass/volume
We know that, 1 cm³ = 0.001 L
V = 2.75 L
So, the volume of liquid glycerol is 2.75 L.
Answer:
The best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"
Explanation:
A buffer is a solution that is somewhat resist to pH changes by reacting with acids and bases that may be added into the solution. It's capacity is the amounto of acid or base that can be added into solution without much change in pH.
So the best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"
What's the difference between A and C because that's the correct answer
Answer:
4.94x10^24 atoms Zn
Explanation:
By definition, there are 6.022x10^23 atoms in a mole of a substance. This is a conversion factor:
(6.022x10^23 atoms/mole)
(8.2 moles Zn)* (6.022x10^23 atoms/mole) = 4.94x10^24 atoms Zn
