Answer:
The formula is H202 (hydrogen peroxide, known as hydrogen peroxide)
Explanation:
100%----34g
5, 9783%---X= (5, 9783%x 34g)/100% =2 g
1g---1 atom of H
2g----x= 2g x 1 atom of H/1g = 2 atom of H
100%----34g
94, 0217%---X= (94,0217%x 34g)/100% =32 g
16g---1 atom of 0
32g----x= 32g x 1 atom of 0/16g = 2 atom of 0
Answer:
0.0845 M
Explanation:
First we <u>convert 4.27 grams of potassium iodide into moles</u>, using its <em>molar mass</em>:
- Molar Mass of KI = 166 g/mol
- 4.27 g ÷ 166 g/mol = 0.0257 mol
Now we <u>calculate the molarity of the solution</u>, using <em>the number of moles and the given volume</em>:
- Molarity = moles / liters
- Molarity = 0.0257 mol / 0.304 L = 0.0845 M
I think the answer is D. the upper surface of undergound water.
