How many molecules are there in 0.565 moles of C6H14?
Sauron [17]

Answer:

3.4 × 10^23 molecules

Explanation:

To find the number of molecules present in C6H14, we multiply the number of moles in the compound by Avagadro's number (6.02 × 10^23 atoms).

number of molecules = number of moles (mol) × 6.02 × 10^23?

Number of molecules = 0.565 × 6.02 × 10^23

3.4 × 10^23 molecules

Give two possible reasons why using tap water instead of distilled water could give misleading
hodyreva [135]

Answer:

Explanation:

Public tap water is not desirable when carrying out experiments in the laboratory.

The chemical definition of water is a compound made up of two atoms of hydrogen to 1 atom of oxygen. Any violation simply desist from the true meaning of water.

Why are tap water not used:

  • They contain other dissolved ions like chlorine which have been added in their treatment. This alters the fundamental molecules that is expected to be seen in water. Water of this nature can affect experimental results seriously.
  • Tap water can become a mixture instead of a simple compound. A mixture is a combination of several compounds. Such water will have a varied composition and make simplification of experiments very difficult.
