Explanation:

Hello!

Let's solve this!

The empirical formula says how many moles of each element are in the compound, but determined experimentally.

The molecular formula is the formula that indicates which elements make up the compound and how many there are of each element.

So to answer your question An empirical formula of a compound is the simplest whole-number ratio of atoms of the elements in the compound. The molecular formula of a compound is either the same as its experimentally determined empirical formula, or it is a simple whole-number multiple of it.

Answer:

1) km 2) cm^ 3) no units (kg cancels) 4) g/cm^3 5) g 6) g°C

Explanation:

Like units will cancel ((m/km)*(km) = m

Non-cancelled units remain (ml)*(g/ml)*(°C) = g°C

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 is the name of this alkane? two central carbons are bonded to c h 3 at each end, h below, and c h3 above the left carbon an

Kazeer [188]

The name of this alkane is with central carbons are bonded to c h 3 is 2-methylbutane.

<h3>What is alkane?</h3>

Alkanes belong to the family of saturated hydrocarbons with carbon carbon single bond.

For the given alkane;

CH₃ H

CH₃ - C - C - CH₃

H H

Thus, the name of this alkane is with central carbons are bonded to c h 3 is 2-methylbutane.
