For a 3.00 aqueous solution of Koh contains 195 g of Koh. The solution has a density of 1.29 g/ml and is mathematically given as

molarity = 1.16L

molarity of solution = 0.946M

percentage concentration = 5%

Generally, the equation for molarity is mathematically given as

molarity = no of moles/ volume in liters

no of mol = 195/56.1

no of mol = 3.48

molarity = 3.48/3.00

molarity = 1.16L

therefore,

mass = 1.29 g/ml x 3000mL

mass = 3.87kg/mL

mass of solute is

= 3.87-0,195

= 3.675

molarity of solution

= 3.48/3.675

molarity of solution = 0.946M

In conclusion, the percentage concentration is

= 195/3870 x100

percentage concentratio = 5%

Answer:

A

Explanation:

To calculate questions like this, you need to make use of the equation below:

E = hν

E is the energy, h is Planck's constant, and ν is the frequency.

Also, another important formula you need for this question is the following:

ν = c / λ

ν is the frequency, c is the speed of light, and λ is the wavelength.

Therefore, E = hν = hc/λ.

Also remember to convert nm wavelength to meters.

To answer the question, E = hc/λ = ((6.626*10^-34 J•s)(3*10^8 m/s))/(4.45*10-7 m) = 4.42 • 10^-19 J = A

Answer:

Average atomic mass = 63.62 amu

Explanation:

Average atomic mass is the weighted average of the individual isotopes.

And thus the weighted average =

(0.6917×63+0.3083×65)⋅amu = ?? amu.

Note that we have not accounted for the less massive copper isotopes that would decrease this mass to the accepted value of

63.55 amu.

Hope this helps! Good luck!

Answer:

a liquid cooling

Explanation:

Liquid cooling results in liquid (more disorder) turning to solid (less disorder).

Entropy describe disorder in our system. Going from more disorder to less disorder decreases entropy.

Rest of the options increase entropy b/c gas escaping from tire releases gas from confined shape to vast environment, snow melting turns solid (order) into liquid (less order), and salt dissolving turns solid into liquid form.

Answer:

[H3O+] = 1.4*10^-5 M

pH = 4.85

[OH-] = 7.08*10^-10

Explanation:

As pH is a measure of hydronium H3O concentration, simply substitute [H3O+] into the following equation:
pH = -log[H+]
pH = -log(1.4*10^-5)
pH = 4.853871...
Round to 2-3 sig figs due to only being given data with 2 significant figures
pH = 4.85

One method to get to [OH-] is to turn pH into pOH and then use inverse functions to get [OH-]
pH + pOH = 14
4.85 + pOH = 14
pOH = 9.15

Then to get [OH-] from pOH:
pOH = -log[OH-]
9.15 = -log[OH-]
-9.15 = log[OH-]
10^(-9.15) = [OH-]
7.07945784 * 10^-10 = [OH]
Round based on given significant figures again:
7.08*10^-10 = [OH-]

(Feel free to add any questions & I'll be sure to reply if clarification is needed)

[H₃O]=1.4 x 10⁻⁵

pH = 5 - log 1.4

pOH = 9 + log 1.4

[OH⁻] = 1 x 10⁻¹⁴ : 1.4 x 10⁻⁵ = 7.14 x 10⁻¹⁰

mol of excess acid: 50 cm ³x 0.05 M = 2.5 mlmol

mol of acid reacted: (250 cm³ x 0.05 M) - 2.5 mlmol = 10 mlmol = 10 x 10⁻³ mol

MM (molar mass) MO = mass : mol = 0.28 : 10 x 10⁻³ =  28

MM MO = Ar M + Ar O

28 = Ar M + 16

Ar M = 12

A line connecting five stars together

Explanation:

Constellations or patterns (same thing) are made up of stars. The stars form shapes, but there is not really lines in the sky. We have to draw the lines with our head or take a picture of it and draw lines on it. Some patterns are: the big dipper, the small dipper etc. Last but not least, just some random info about the constellations.. zodiac signs have their own constellations. Here is a list of the zodiacs to their constellations:

•Leo (the Lion)

•Aquarius (the Water Bearer)

•Gemini (Twins)

•Cancer (Crab)

•Aries (Ram)

The quantity of SF6 that we can get is = 228.2g

The quantity of S that reacted = 50g

The quantity of F2(g)that reacted = 105.0g

Therefore the quantity of SF6 that will be produced = ?

But molar mass of sulphur = 32g/mol

molar mass of SF6(g)= 146.06 g/mol

If 32g of S = 146.06 g of SF6

50 g of S = x

Make X the subject of formula,

X = 50×146.06/32

X = 7303/32

X = 228.2g of S

Explanation:

molarity=moles/volume

moles=5.10/180.16

Alcohols have higher boiling points than do ethers and alkanes of similar molar masses.

The temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid is called the boiling point of the substance.

Approximately boiling point of Ethanol: 78.4°C, ether: 34.6°C, ethanes: 68°C

The reason for the difference is that it takes more energy to separate alcohol molecules then it does to separate alkane molecules and ether molecules.

The OH group in  alcohol allows molecules to engage in hydrogen bonding.

Therefore Boiling point are in the order ;

Alcohol > alkane > ethers
