The formula ca(no3)2 tells us that one formula unit of this compound is composed of ________ calcium atoms, ________ nitrogen at
ad-work [718]

Answer:- The formula Ca(NO_3)_2 tells us that one formula unit of this compound is composed of one calcium atom, two nitrogen atoms, and six oxygen atoms.

Explanations:- Subscripts tell us about the number of atoms of the element for which they are used. For example, here the subscript of Ca is one, it means there is one calcium atom in the given one formula unit.

When we have subscripts inside and outside the parenthesis then they are multiplied and the outside subscript is considered for all the atoms present inside the parenthesis.

Here, for the given chemical formula, the subscript of N is 1 and the subscript present outside is 2. So, 1 x 2 = 2 and for oxygen, 3 x 2 = 6

So, we have one calcium atom, two nitrogen atoms and six oxygen atoms for one formula unit of given compound.

What is the molarity of a solution in which 250 grams of NaCl are dissolved in 2.9 L of water?
Maksim231197 [3]

Answer:

About 1.48 M.

Explanation:

The formula for molarity is mol/L.

So firstly, you must find the amount of moles in 250 grams of NaCl.

I do this by using stoichiometry. First, I find how nany grams are in a single mole of NaCl. This is around 58.44 grams/mole. Now that I know this, I can now use a stoich table. (250 g NaCl * 1 mol NaCl / 58.44 g NaCl). I plug this into my calculator.

I get that 250 grams of NaCl is equal to about 4.28 moles.

Now I just plug into the formula!

4.28 moles/2.9 L = about 1.48

<em><u>I've</u></em><em><u> </u></em><em><u>attached</u></em><em><u> </u></em><em><u>a </u></em><em><u>picture </u></em><em><u>of </u></em><em><u>my </u></em><em><u>personal </u></em><em><u>notes </u></em><em><u>below </u></em><em><u>which </u></em><em><u>shows </u></em><em><u>work </u></em><em><u>I </u></em><em><u>have </u></em><em><u>done</u></em><em><u> </u></em><em><u>in </u></em><em><u>similar </u></em><em><u>equations.</u></em>
