Understanding the Concepts
* Molarity (M): Molarity is a measure of concentration, defined as moles of solute per liter of solution.
* Moles (mol): A mole is a unit of measurement for the amount of substance.
Calculation
1. Use the Molarity Equation:
Molarity (M) = moles of solute (mol) / volume of solution (L)
2. Rearrange the equation to solve for moles:
moles of solute (mol) = Molarity (M) * volume of solution (L)
3. Plug in the given values:
moles of H2SO4 = 2.0 M * 5.0 L
4. Calculate:
moles of H2SO4 = 10.0 mol
Answer: You would need 10.0 moles of H2SO4 to prepare 5.0 liters of a 2.0 M solution.
