Answer:
Number of moles is defined as the ratio of given mass in g to the molar mass.The mathematical expression is given as:
Number of moles =Number of moles of compound = 12.7 moles (given)As, 1 mole of any compound is equal to particles.
where, is Avogadro number. Formula for calculating particles is given by:
where, N = number of particles, n = number of moles and is Avogadro number.
Put the values,= or Hence, number of particles of the compound is equal to
Explanation:
Answer:
Copper
Explanation:
Metals are often arranged in crystalline lattices. The lattice consists of metal ions with an overlying sea of electrons. The conductivity of a metal depends on the nature of this crystal lattice. Naturally, some metals conduct electricity better than others. The unique properties of the crystal lattice of copper allow electrons to flow through it freely especially when it is drawn into a wire.

Answer:
8 possible microstates.
Explanation:
Supposed we tossed three (3) coins (a nickel, a dime, and a quarter).
The possible outcomes can be seen as follows.
Coin
1st. +1 +1 +1 -1 +1 -1 -1 -1
2nd +1 +1 -1 +1 -1 +1 -1 -1
3rd +1 -1 +1 +1 -1 -1 +1 -1
There 8 (eight) microstates are possible.
