The question is incomplete, here is the complete question:

A chemist prepares a solution of sodium thiosulfate by measuring out 110. g of sodium thiosulfate into a 350. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's sodium thiosulfate solution. Be sure your answer has the correct number of significant digits.

<u>Answer:</u> The concentration of sodium thiosulfate solution is 1.99 mol/L

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

Given mass of sodium thiosulfate = 110 g

Molar mass of sodium thiosulfate = 158.1 g/mol

Volume of solution = 350 mL

Putting values in above equation, we get:

$\text{Molarity of sodium thiosulfate}=\frac{110\times 1000}{158.1\times 350}\\\\\text{Molarity of sodium thiosulfate}=1.99mol/L$

Hence, the concentration of sodium thiosulfate solution is 1.99 mol/L

In the article "A Sea of Garbage" what message is each cartoon trying to convey to readers? Do they succeed?

sertanlavr [38]

Answer:

yes in the article I see of garbage what's messages each carton trying to convey to your readers with a success obviously they do suck said they succeed because like that's really great day socks said is your garbage is like a pool of garbage work garbage are gathered together they are together a you get one talking about you know when cabbage and together they make efficient use of them okay I mean garbage garbage garbage garbage so I don't know I don't know I don't know I don't know I don't know but it's really is regret it regret it was someone couldn't wish for our young people pick them up and see if garbage and it's really not making sense cuz when you see a sea of garbage that means there's water in there and people pull up garbage in be like water pollution or something but I'm actually not really like sure but I have a slight idea of like what we talking about here right now and it's great
