What is the molariity of a 50.0 mL aqueous solution containing 10.0 grams of table salt, NaCl?
tia_tia [17]

Answer:

3 mol/L

Explanation:

You should know or have the equation to solve for Molarity which is;

M = n/v           (M: Molarity) (n: moles of solute) (v: Liters of solute)

You can start off differently but I would start by converting the mL to L. This is your "v" value.

50.0 mL/ 1000 mL = 0.05 L

Now, you have to convert grams to moles in order to solve for molarity (M).

1.) On the periodic table find the molecular weights of Na and Cl.

Na= 22.99 g/mol         Cl= 35.45g/mol

2.) Add them together to have their combined molecular weights.

22.99 + 35.45= 58.44 g/mol

3.) Now, you're going to use the "picket fence method" or whichever your teacher taught you to convert from grams to moles. This will be your "n" value. (I cannot show it on here without it looking weird, so my sincere apologies.)

10.0 g/ 58.44 g = 0.17111 mol

4.)You are now going to plug in your answers into the equation for Molarity.

M= 0.17111 mol / 0.05 L = 3.4222

5.) I am sure your professor might be a stickler so for sig figs sake when you multiply or divide use the smallest amount of sig figs you see which is 1. Round 3.4222 to 3 mol/L

Sorry this explanation is long let me know if you need a better more written out sample.

Energy comes in different forms.
LenKa [72]

Answer:

liquid, solid, and gas

Explanation: It depends where the molecules are moving. When a solid the molecules are vibrating and are all together, compact, the molecules are also very slow. When a liquid the molecules are moving back and forth, up and down, and are less compact, but moving faster. When a gas, the molecules move everywhere very quickly, moving super fast.

If the concentration of sugar in water is determined to be 45 g/100 ml and 135 g of sugar was used to make the solution how much
-BARSIC- [3]

Answer:

300g of water was used to make the solution

Explanation:

In the sugar solution, there are dissolved 45g of sugar in 100mL of water. The conversion factor is <em>45g Sugar = 100mL water</em>. That means when 135g of sugar are used the amount of water is:

135g sugar * (100mL water / 45g sugar) =

<h3>300g of water was used to make the solution</h3>
