Answer 1

Answer:

• 75M is the molarity.

Explanation:

Given:-

• 9.8g of H₂SO₄ is dissolved in 750ml.

To find:-

• Molarity of the solution.

Solution:-

We know,

• M.V = grams/molar mass

We have,

Molar mass of H₂SO₄:

• 1(2) + (32) + 4(16)
• 98g

Volume:

• 750ml

Grams:

• 9.8g

Hence,

› x × 750/1000 = 9.8/98

› x × 7.5 = 0.1

› 7.5x = 0.1

› x = 7.5/0.1

∴ x = 75

∴ Molarity of the solution is 75 M.
