Answer:
The mass of an average copper atom is
Explanation:
Given:
The total mass of copper atoms,
Number of atoms,
Now, we are asked to find the mass of 1 copper atom.
We use unitary method to find the mass of 1 copper atom.
Mass of atoms = m
∴ Mass of 1 atom =
Plug in 63.5 for 'm', for 'N' and simply.
Mass of 1 atom =
Therefore, the mass of an average copper atom is
Option C Na2 SO4.
Because the Na2 SO4 produces 3 mols for every mol of Na2 SO4 dissolved and the increase in the boiling point is proportional to the number of mols dissolved.

Answer:
James West impacted his field in an abundance of ways. For example, West and Sessler are credited as the inventors of the “foil electret microphone”. Without the creation of this compact microphone over 90 percent of all contemporary microphones – which includes those found in telephones, tape records, baby monitors and hearing aids would cease to exist today.
<u>Answer:</u>
<em>We know water can exist in all three states be it solid or liquid or gas the only difference between the three states is the temperature at which they exist. </em>
<u>Explanation:</u>
When the temperature moves towards colder region the state of water changes to solid while when the temperature moves to water region the state of water changes to gas.
This little experiment can be done with the help of ice at room temperature. The more ice is applied to water it will turn to ice but removal of eyes in room temperature. And will make it turn to water and complete removal of eyes with application of heat would make it into vapour.
