A strontium hydroxide solution is prepared by dissolving 10.60 gg of Sr(OH)2Sr(OH)2 in water to make 47.00 mLmL of solution. What is the molarity of this solution? Express your answer to four significant figures and include the appropriate units.

Approximately .

Explanation:

Note that both figures in the question come with four significant figures. Therefore, the answer should also be rounded to four significant figures. Intermediate results should have more significant figures than that.

Look up the relative atomic mass of , , and on a modern periodic table. Keep at least four significant figures in each of these atomic mass data.

Calculate the formula mass of :

.

means that each mole of formula units have a mass of .

The question states that there are of in this solution.

How many moles of formula units would that be?

.

There are of formula units in this solution. Convert the unit of volume to liter:

.

The molarity of a solution measures its molar concentration. For this solution:

.

(Rounded to four significant figures.)

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.
