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?
To find the number of argon atoms in a 40.0-g sample, you first need to calculate the number of moles of argon in the sample using the molar mass of argon (39.95 g/mol). Then, you can use Avogadro's number (6.022x10^23 atoms/mol) to determine the number of atoms in that many moles of argon.
How many atoms in a molecule of argon?
There is one atom in argon. Argon is a "noble gas", which means that it occurs independently. This is true for all of the atoms on the final column of the periodic table. http://en.wikipedia.org/wiki/Noble_gas
What is the formula for argon trifluoride?
Formula: ArF3 But this compound does not exist
How many protons neutrons and electrons are present in one atom argon?
There is more than one isotope of argon (as there are of all elements) but the most common isotope is the one that has an atomic weight of 36; it has 18 protons, 18 neutrons, and 18 electrons. The same number for all three types of particles.
Is argon a heterogeneous mixture or a homogeneous?
First of all Argon is not a mixture , it is an elementArgon is colorless odorless, and tasteless.
Is Ar a atom or molecule?
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.

What is the mass of a single argon atom in grams?
Since Argon has a relative atomic mass of 39.95, and mols = grams / RAM, one could calculate 39.95 / (6.02*10^23) = 6.63 * 10^-23 grams [0.00000000000000000000006634g] for a single argon atom, where 6.022 * 10^23 is roughly Avogadro's constant (the count of atoms in a mole). IF my math is correct.
Which one has the largest atom helium or argon?
Niether. In 2015, the largest known atom belonged to ununoctium.

How do you calculate the number of sweets in a jar?
Calculate the volume of one sweet. Calculate the volume of the jar and then divide the volume of the jar by the volume of a sweet.
Give a method to measure size of the atom using Avogadro hypothesis?
One way to measure the size of an individual atom using Avogadro's hypothesis is to calculate the volume occupied by one mole of the element. By dividing Avogadro's number (6.022 x 10^23) by the density of the element, you can determine the volume of one mole of atoms. Finally, by dividing this volume by Avogadro's number, you can find the approximate volume occupied by a single atom.
What is one atom of noble gas?
For example one atom of helium, one atom of argon etc.; all atoms contain a nucleus (formed from protons and neutrons) and a cloud of electrons.
What is the formula for argon trifluoride?
Formula: ArF3 But this compound does not exist
How many chemical bonds in one atom of argon?
Argon is a noble gas element. It has a saturated electronic configuration i.e ns2, np6. So it has a octet configuration. It is already attained stable configuration. Also it has high ionisation energy. Small in atomic size. From the above it is confirmed that it exists in atomic state only and not is molecular form. Therefore chemical bond will be zero in an atom of argon.
What element has 18 neutrons in its atom?
There are several. However, Chlorine is one. Chlorine-35 has 17 protons, 18 neutrons and 17 electrons in its isotopic atom. However, Chlorine-37 has 17 protons, 20 neutrons and 17 electrons in its isotopic atom.
What gas in air has more than one atom?
Oxygen, nitrogen, argon have diatomic molecules.
