An acid has a molarity of 0.01 M. What does the 0.01 M refer to?
Delvig [45]
So molarity which is represented by that 0.01M refers to the amount of moles that is present in 1L or 1dm³ of the substance, in this case the acid.  Molarity refers to CONCENTRATION therefore and has little to do with the strength of the acid (the strength is dependent on the pH).

Thus your answer is OPTION B

If you have 2 water molecules together, would you expect them to sit "hydrogen by hydrogen" or "hydrogen to oxygen"? Why?
kondor19780726 [428]

Answer:

"hydrogen to oxygen"

Explanation:

Hydrogen bonds are formed when hydrogen is bonded to highly electronegative element such as Chlorine, fluorine, oxygen etc.

In hydrogen bonding, the hydrogen atom of one molecule of water is attracted to the oxygen atom of another molecule of water via permanent dipole-dipole interaction.

Hence, If you have 2 water molecules together, they always sit "hydrogen to oxygen" as a result of dipole - dipole interaction and  hydrogen bonding between water molecules.

How many atoms of K are present in 195.49 grams of K? 3.0110 × 1024 6.0220 × 1024 1.1772 × 1026 4.5797 × 1027
Ierofanga [76]
<h2>Hello!</h2>

The answer is: 3.0110x10^{24}

<h2>Why?</h2>

First, we need to look for the K molecular mass:

K=39,098 g/mol

Also, we need to remember that 1 mol of a compound or element is equal to 6,022x10^{23} of that compound.

From the statement, we are asked to calculate how many atoms of K are present in 195,49 of K.

So, doing the calculations, we have:

195,49g*\frac{1mol}{39,08}*\frac{6,022x10^{23} atoms}{1 mol K} =3,0110x10^{24} \\

So, we have 3.0110x10^{24} atoms of K in 195,49 grams of K.

Have a nice day!
