How many moles of H2SO4 are needed to prepare 200 mL of a 1.0 M solution?

To find the number of moles required, use the formula:

Molarity (M) = moles / volume (in liters)

Step 1: Convert volume to liters

200 mL = 0.2 L

Step 2: Apply formula

moles = M × V

moles = 1.0 × 0.2

moles = 0.2 mol

Final Answer:

0.2 moles of H₂SO₄ are required

Key Takeaway:

Use the formula moles = molarity × volume (in liters) to calculate required moles for solution preparation.
