Asked in Chemistry
What is molar mass of tap water?
For clarification: Molar mass, meaning mass per one mole of the molecule. eg: one mole of water = H2O, two moles of water = 2H2O It really depends where the tap water is from. Besides that tap water is a mixture, not a compound. (The ions are not all bonded) So it doesn't have a chemical equation.. If I were you I'd just use the Molar Mass of pure water in your calculations, or ask the teacher. (H = 1.008, * 2 = 2.016 O = 16.00 Molar Mass of H2O =2.016 + 16.00 = 18.016 g/Mole)

What is the difference between tap water and bottled water?
How long must the tap water sit before using it to change a Betta fish tank?
Answer Just be sure the temperatures are the same IF you are using a tap water dechlorinator. Letting it sit 30 minutes will do or you could play with the water temperature until it is the same. However, if you do NOT have any tap water dechlorinator, then let the water sit for 48 hours (or at least 24 hours) to get rid of the chlorine and other harmful chemicals in the tap water.

Why is it best not to use tap water for a fish tank?
The only thing wrong with using tap water is all the possible impurities that may be in the tap water. If you've ever noticed, tap water tastes different than bottled water. That's because of the other impurities in the tap water, and some impurities are bad enough to kill a fish, but not humans. I use tap water for both of my tanks with no problem, either leave it over night in a bucket or treat it with dechlotinator and you are set.
