The molarity of KOH is 0.98 M.

<u>Explanation:</u>

KOH + HBr →KBr + H₂O

As per the above reaction, equal moles of KBr and HBr reacts to form 1 mole of KBr and 1 mole of water. We have to find the molarity of KOH by using the law of Volumetric analysis using the equation as,

V1M1 = V2M2

Here V1 and M1 are the volume and molarity of HBr.

V2 and M2 are the volume and molarity of KOH .

We can find the molarity of KOH as,

$ M2= \frac{V1\times M1}{V2}

Plugin the values as,

$ M2 = \frac{15.40 ml \times 1.4 M}{22.10 ml}

    =  0.98 M

So the molarity of KOH is 0.98 M.

What type of bond forms between two oxygen atoms
mr_godi [17]

Answer:A double convalescent bond is where two pairs of electrons are shared between the atoms rather than just one pair. Two oxygen atoms can both achieve stable structures by sharing two pairs of electrons as in the diagram.

How many moles of carbon atoms are present in a piece f diamond?
NNADVOKAT [17]
Diamond is an allotrope of carbon; that just means it is a different crystalline structure, but pure diamond contains only carbon atoms. (unrelated, but interesting - colored diamonds come from impurities like boron and nitrogen in the crystal structure!) The molar mass of carbon is 12.01 g/mol. You can find the molar mass by looking at the periodic table. If you look under number 6, Carbon, you should see the atomic weight right under it: 12.01. The molar mass is this same number, in grams. That means that one mole, or 6.022E23 carbon atoms, weigh 12.01 grams. 
<span>But you don't have one mole. You only have 2 grams. </span>
<span>So how many moles do you have? 2 grams out of 12 grams. 2/12 = 1/6 or 0.167. You have 1/6th of a mole. One mole is 6.022E23 atoms, but you only have 1/6th of that. I hope that thinking about it stepwise like this makes sense to you. It works the same for other atoms and molecules too. In a molecule, you would just add up the molar mass of all the component atoms. I hope this helps.
