How many atoms are there in 3.5 moles of arsenic?

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.


What is Avogadro's number the number of?

The number of elementary entities in a mole of the substance. The elementary entities depends on the particles making up the substance. For example, argon is made of single atoms, so a mole of argon simply contains Avogadro's number of atoms. Water, on the other hand, is made of molecules, so a mole of water contains Avogadro's number of molecules. Now each water molecule, H2O, contains 3 atoms so a mole of water contains 3xAvogadro's number of atoms. Sodium chloride, NaCl, is made of sodium and chloride ions, in a ratio of 1:1. So a mole of sodium chloride contains Avogadro's number of sodium ions, and Avogadro's number of chloride ions. A mole of sodium chloride therefore contains 2xAvogadro's number of ions in total. The number comes from the number of carbon atoms in 12g of carbon-12.

How many protons nuetrons and electrons does argon have?

In order to answer this question, the specific isotope of argon must be known. However, I will answer it using argon-40 because it makes up over 99% of the atoms of argon. Argon-40 has a mass number of 40, meaning that the sum of protons and neutrons in the nuclei of its atoms is 40. In order to use this information to determine the numbers of protons and neutrons, you also need to know the atomic number, which is the number of protons in the nucleus of its atoms. Argon's atomic number is 18, so we know that all argon atoms have 18 protons. To calculate the number of neutrons, we subtract the atomic number from the mass number, which is (40-18)=22 neutrons. The number of electrons equals the number of protons in a neutral atom, so argon atoms have 18 electrons. So, to sum things up, neutral atoms of argon-40 contain 18 protons, 22 neutrons, and 18 electrons.


How many moles are in 3.0x1024 atoms of argon?

A mole of argon includes Avogadro's Number of atoms of argon. Therefore, the answer is (3.0 X 1024)/(6.022 X 1023) or 5.0 moles, to the justified number of significant digits.


The actual mass of an atom of argon is is 6.63x10-24g How many atoms are in a 40.0-g sample of argon?

Divide 40g by the mass of one atom to find the number of argon atoms.


Do all of atoms of argon have same atomic number?

Yes


Do all atoms of argon have the same atomic number?

Yes


How many protons do Argons have?

Argon atoms have 18 protons which is similar to the number of electrons.


How many atoms of argon are in one mole?

The number is Avogadro's number, 6.0221409 *10^23


How do you tell that there is 33 electrons in arsenic?

A neutral atom has equal numbers of positively charged protons and negatively charged electrons. The atomic number of an element is its number of protons. Arsenic's atomic number is 33, so atoms of arsenic have 33 protons. A neutral atom of arsenic would then also have 33 electrons.
