- Molarity = moles of solute / liters of solution
<h3>
Explanation:</h3>
<u>Step 1: Define</u>
[Given] 2.14 moles (CH₃)₂SO
[Given] 2.00 L
[Solve] Molarity
<u>Step 2: Solve</u>
- Substitute in variables [Molarity]: x M = 2.14 moles (CH₃)₂SO / 2.00 L solution
- [Molarity] Divide: x = 1.07 M
They are about 4.5 billion years old. Hope this helps.
Answer:
<u>49 moles of atoms</u>
Explanation:
There are 7 individual atoms in each molecule of H2SO4: (2 hydrogens + 1 sulfur + 4 oxygens).
Therefore, if 7 moles are decomposed, there would be 7 times that amount of individual atoms:
7 x 7 = 49 moles of atoms
