Answer:

2000 mL

Explanation:

Given data:

Number of moles KMnO₄ = 6 mol

Molarity of solution = 3M

Volume of solution in mL = ?

Solution:

Formula:

Molarity  = number of moles of solute / volume of solution in L

3 M = 6 mol / volume of solution in L

volume of solution in L = 6 mol/ 3 M

volume of solution in L = 2 L

Now we convert the L into mL:

1 L = 1000 mL

2 L × 1000 mL / 1 L

2000 mL

DNA is packaged into these<br> compact units
Wittaler [7]

Explanation:

Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Each nuclesome is composed of DNA wound 1.65 times around eight histone proteins.

The dipole measured for HI is 0.380 D. The bond distance is 161 pm. What is the percent ionic character of the HI bond?
Feliz [49]

Answer:

Percent ionic character of HI bond is 4.91%.

Explanation:

<h3>Given Data:</h3>

Measured Dipole = 0.380D

bond distance = d = 161pm = 1.61*10^-8 cm

<h3>Calculation:</h3>

% ionic character is determined by following equation:

% ionic= (dipole measured/dipole calculated)*100

Now,

Dipole(calc)=qd

Dipole(calc)= (1.6*10^{-19}*3*10^{9})esu  *1.61*10^{-8}cm

(In above step 3*10^8 is multiplied to convert coulomb into esu)

Dipole(calc)=7.728*10^{-18} esu*cm

As,

10^{-18}esu*cm= 1D

So,

Dipole(calc)=7.728D

Now we can % ionic character using above equation:

%ionic=(0.380D/7.728D)*100

% ionic character=4.91%

How does temperature, pressure and surface area affect the dissolving process
larisa [96]
If I am correct, yes. As I was told in chemistry, the surface area affects the dissolving of the "sugar". If you put regular Surat in a hot cup of coffee, it will dissolve at a quick pace, but what if you put the same amount of sugar in the same amour of coffee, but the sugar was fine powder? It would dissolve even faster since it has more surface area. So temperature does affect the dissolving. Hope this helps!

How would a solute affect the boiling point of water?
Alex787 [66]
The answer is C. The water will boil at a higher temperature. This is because the solute is an impurity that raises the boiling point and lowers the melting point of water.

Is this correct? also for the mass i have to round it to the closest whole number
11Alexandr11 [23.1K]
A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Overall charge is +1
