How do you determine the number of water molecules in a hydrate?

Example One

  1. Take the mass of the hydrate and subtract the mass of the anhydrate to get the mass of water.
  2. Divide the mass of water by the molar mass of water to get moles of water.
  3. Divide the mass of anhydrate by the molar mass of anhydrate to get moles of anhydrate.

What is the formula of the hydrate CuSO4?

Can tree roots grow through PVC pipe?

While tree roots can penetrate PVC pipe, it’s more durable and does not break down as easily as other materials. If you’re planting trees on your land, consult a map of existing underground sewer lines and avoid planting problematic trees nearby.

How do you know if you have tree roots in your pipes?

How much does it cost to fix roots in pipes?

Digging and replacing a sewer line costs $50 to $200 per foot, or from $3,000 to $30,000. Most sewer pipe repairs range from $1,500 to $4,000 if the problem is 10 feet of pipe or less. Excavation is typically included by your plumber, else, trenching costs $6 to $15 per foot.

Is Roto Rooter cheaper than a plumber?
