C. 0.1 M HCl

Explanation:

The solution with the lowest molarity is the most dilute of all.

This is why the choice is 0.1M of HCl.

Molarity is the same as concentration. The unit "M" denotes mole per liter volume of solution.

Molarity is defined as the number of moles of solute in a give volume of solution.
0.1M means 0.1mole of HCl is dissolved in 1liter of solvent.
The higher the number of moles dissolved and the more the concentration of the solution will be.

The order of increasing concentration is:

0.1M < 0.2M< 0.3M < 0.4M

Calculate the molar solubility of silver(i) bromate with ksp = 5. 5×10-5. also, convert the molar solubility to the solubility.

Sindrei [870]

The molar solubility is 7.4× $10^{-3}$ M and the solubility is 7.4× $10^{-3}$ g/L .

Calculation ,

The dissociation of silver bromide is given as ,

$AgBr$ → $Ag ^{+}$ + $Br^{-}$

- S S

Ksp = [ $Ag ^{+}$ ] [ $Br^{-}$ ] = [S] [ S ] = $S^{2}$

S = √ Ksp = √ 5. 5× $10^{-5}$ = 7.4× $10^{-3}$

The solubility =7.4× $10^{-3}$ g/L

The molar solubility is the solubility of one mole of the substance.

Since , one mole of $AgBr$ is dissociates and form one mole of each $Ag ^{+}$ and $Br^{-}$ ion . So, solubility is equal to molar solubility but unit is different.

Molar solubility = 7.4× $10^{-3}$ mol/L = 7.4× $10^{-3}$ M

What if you measured 15cc of liquid elemental mercury, how much would that weigh in pounds

PIT_PIT [208]

Answer:

0.447 pounds

Explanation:

The density of Mercury in grams/mL is 13.55 - I multiplied that by the volume and got approximately 203.25 grams, I then turned it into Kilograms and multiplied by 2.2 lbs / kg.
