The number of electrons in a mole of any substance would be Avogadro's number times its atomic number (if an element) or times the sum of the atomic numbers of its molecule (if a compound) So, since the atomic number of Al is 13, the number of electrons is (6 X 10^23) X 13 = 78 X 10^23. Give or take a few.

One mole of silicon (Si) has a mass of 28.086 g and one mole of carbon has a mass of 12.011 g. What is the mass of one mole of silicon carbide (SiC)?
28.086 g + 12.011 g = 40.097 g
Which would contain more electrons a mole of K atoms or a mole of Au atoms?
Let's see. 1 mole K atoms = 6.022 X 1023 atoms * 19 electrons = 1.144 X 1025 electrons in one mole potassium ------------------------------------------------------------- 1 mole Au atoms = 6.022 X 1023 atoms * 79 electrons = 4.757 X 1025 electrons in one mole gold ------------------------------------------------------ A mole of gold, Au, atoms contains more electrons than a mole of potassium, K, atoms.
How many valence electrons are in Si 2-?
The normal valance number of silicon is 4, so with Si 2- one knows that silicon now has 6 electrons in it's valence shell.

How many moles of electrons are present in 17 grams of ammonia?
There are 10 electrons per molecule of NH3,17g of ammonia means one mole, therefore 10 moles of electrons are present.
How many valence electrons are present in silicon?
The valency of silicon is 4. This means that this atom has the tendency to behave as if it had 4 'hooks'. Basically, silicon is ready to take on 4 electrons with which it would secure the same electronic configuration as Ar (argon) which is one of the most stable, non-reacting gases, and this is what most atoms are aiming for; a stable state.
Find out number of electron's in one mole of sodium ion?
Find out number of electron's in one mole of sodium ion? 1 mole of atoms = 6.02*10^23 atoms 1 mole of electrons = 6.02*10^23 electrons A Na atom has 11 protons and 11 electrons. Protons have a +1 charge and electrons have a -1 charge. A Na ion has 1 less electron than a sodium atom. One Na ion has 10 electrons. 1 mole of Na ions = 6.02*10^23 ions Each Na ion has 10 electrons. 1 mole of Na ions = 10 * 6.02*10^23 ions 1 mole of Na ions = 6.02*10^24 ions
How many grams in one mole of silicon?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Selenium's atomic mass is 78.96 grams.
