In one mole of Arsenic contains 6.02 x 10^23 atoms. This is the Avogadro's number. So in 3.5 moles of Arsenic, there would accordingly be 2.11 x 10^24 atoms.
A mole of As has the Avogadro number of moles. It is equivalent to 6.022 x 10^23. Therefore, 3.5 moles of the element contains 2.11 x 10^24 atoms of Arsenic.

∙ 14y agoA mole of anything is 6.22x1023, just like a dozen of anything is 12. 155 moles of arsenic would have:
(155 moles As) x (6.22x1023atoms/mole) = 9.64x1025 atoms of As

∙ 13y ago1.5 moles arsenic (6.022 X 10^23/1 mole arsenic)
= 9.0 X 10^23 atoms of arsenic

∙ 12y agoSince the formula mass for arsenic is generally considered to be that of a single atom, the answer is 3.5 times Avogadro's Number or 2.1 X 1024, to the justified number of significant digits.

How many atoms in 35 mol carbon dioxide?
1 mol of any substance contains 6.02 x 1023 constituent particles. This is the avogadro constant. So in 35 moles of CO2, there would be 35 x 6.02 x 1023 molecules of CO2. In each CO2 there are three atoms (one carbon and two oxygen). Therefore the total number of atoms in 35mol of CO2 is 3 x 35 x 6.02 x 1023 = 6.32 x 1025
What is the molarity of sodium sulphate in a solution prepared by dissolving 15.5g in enough water to make 35ml of solution?
Molarity = moles of solute/volume of solution Find moles NaCl 55 grams NaCl (1mol NaCl/58.44 grams) = 0.941 moles NaCl Molarity = 0.941 moles NaCl/35 Liters = 0.027 Molarity NaCl ( sounds reasonable as 55 grams is not much in 35 Liters of water, which would be about 17.5 2 liter sodas )
What mass of tungsten is 35 moles of tungsten?
1 mol of Tungstun Weighs 183.85 gso 35 mol Tungstun will weigh 183.85 X 35 g = 6434.75g
What is the number of electrons in bromine-82?
An atom of bromine-82 has 35 protons, 35 electrons and 47 neutrons. All electrically neutral atoms of bromine have 35 electrons.
How many grams of oxygen are in 56 g of c2h2o2?
The molecular weight of ethane (C2H6) is 30.07 so 65.7 g of it would be 2.185 moles. Each mole of ethane burned would yield 2 moles of carbon dioxide - which has a molecular weight of 44.01. You would get 2 x 2.185 x 44.01 = 96.2 g of carbon dioxide Note that the statement of burning with excess oxygen is important because it would push the reaction more to completion and limit the formation of carbon monoxide to an insignificant amount.
How many atoms in 35 mol carbon dioxide?

How many moles are in CF2Cl2?
Well, there are 140 grams of 2Cl2 in one mole of it. You take the atomic mass and find how many atoms and multiply them together. Chlorine has an atomic mass of about 35, so multiply by four b/c there are four Cl atoms in 2Cl2 .
How many moles of C are in 90g of CO2?
