<u>Answer:</u>
Density is mass per unit volume.
Its formula is
Density = Mass / Volume
Its units can be kg/L or kg/() or g/mL or g/(
)
Density of various substances are given. The more denser substance goes to the bottom of the graduated cylinder.
Air on the top then comes Wood followed by Corn oil followed by Ice and then Water followed by Glycerin then Rubber then Corn syrup and at last Steel at the bottom which will more denser than all the substances mentioned above.
The staking up of the substances is in the order mentioned below in the tabular column
Answer:
Ok:
Explanation:
So, you can use the Henderson-Hasselbalch equation for this:
pH = pKa + log() where A- is the conjugate base of the acid. In other words, A- is the deprotonated form and HA is the protonated.
We can solve that
1 = log() and so 10 =
or 10HA = A-. For every 1 protonated form of adenosine (HA), there are 10 A-. So, the percent in the protonated form will be 1(1+10) or 1/11 which is close to 9 percent.
