The acetic acid will dissociate as
We will use Hendersen Hassalbalch's equation here
pH = pKa + log [salt] / [acid]
Where
[Acid] = concentration of protonated form
5.1 = 4.8 + log [salt] / [acid]
1.99= [salt] / [acid]
[salt] +[acid] = 0.5
1.99 [acid] + [acid] = 0.5
[acid] = 0.167 M
[acid] / total concentration = 0.167 / 0.5 = 0.33.4
So percentage = 33.4 % or approx 33 %
A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture, or material type.
Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.
Answer:
![m_{Au_{31}}=6106.07 g](https://tex.z-dn.net/?f=m_%7BAu_%7B31%7D%7D%3D6106.07%20g)
Explanation:
Hello,
In this case, since one gold atom has a mass of 196.97 g, for the given gold cluster that has 31 gold atoms, the mass will be:
![m_{Au_{31}}=31*196.97g\\\\m_{Au_{31}}=6106.07 g](https://tex.z-dn.net/?f=m_%7BAu_%7B31%7D%7D%3D31%2A196.97g%5C%5C%5C%5Cm_%7BAu_%7B31%7D%7D%3D6106.07%20g)
Whereas we consider the mass of all the 31 gold atoms to compute the overall mass.
Best regards.
Answer:
1.10 g/mL
Explanation:
The amount of volume an object displaces is the amount of volume that object takes up.
7.87 - 1.67 = 6.2
The object has a volume of 6.2 mL.
You have the mass (6.82 g) and the volume (6.2 mL). Divide the two value to find the density.
(6.82 g)/(6.2 mL) = 1.10 g/mL
The density of the object is 1.10 g/mL.
