To solve this we use the equation,
M1V1 = M2V2
where M1 is the concentration of the stock
solution, V1 is the volume of the stock solution, M2 is the concentration of
the new solution and V2 is its volume.
65 x V1 = 2 x 200 L
V1 = 6.15 L
The answer is diagram A.
Hope this helped. Good luck!
Answer:
9 Moles
Explanation:
C2H6 has 6 Hydrogens and Water Has 2 Hydrogens
so it takes 1 mole ethane to produce 3 moles water
1 Mole Ethane ----> 3 Moles Water so 3 ----> 9 moles
Answer:
2584 g
Explanation:
The molecular formula for sucrose is C₁₂H₂₂O₁₁, which means its molar mass is 342.3 g/mol.
First we<u> convert molecules into moles</u> by using <em>Avogadro's number</em>:
- 4.55x10²⁴ molecules ÷ 6.023x10²³ mol/molecules = 7.55 mol
Now we <u>convert moles of sucrose into grams</u>, using its<em> molar mass</em>:
- 7.55 mol * 342.3 g/mol = 2584 g
