E since its a physical model i.e. you can touch and feel the model :)
The hypothesis can’t be a opinion or something that has nothing to do with your work
For example;if you want to see if your toilet paper is sturdy and you say “i think it will cause the commercial says it does” (wrong) answer would have to be “i infer that the toilet paper will be sturdy because it looks more resistant than other paper I’ve seen”
Answer:
.224 M
Explanation:
To begin, we need to find the molar mass of Na2S
To find Molarity, we use the equation M=moles/Liters of solution
We are given grams, so we must divide by the molar mass of Na2S to find moles.
- 8.76g Na2S / 78.05g/mol Na2S= .112 moles
Now we use our Molarity equation:
- .112 moles Na2S / .500L of solution = .224 M
