Each element has a different mass and size, therefore cannot be compared to each other in equal quantities with mass alone. In 1g of Carbon there will be a different number of particles than in 1g of Oxygen. The Avogadro's constant states how many particles there are in one mole of an element. By multiplying this constant with the relative Atomic Mass, the number of moles can be worked out, and this then used comparatively between elements.

∙ 13y agothe number of moles is mass in grams divided by relative mass
example how many moles are there in 42g of carbon?
answer 42 / 12 = 3.5 moles
mass in grams divided relative mass = number of moles

∙ 10y agoIf you have the molarity of solution, you can find the moles in a particular set volume by dividing molarity by 1000 and multiplying by the amount of millilitres of the solution that you have. If you have the weight, you divide this by the molecular mass. The weight has to be in grams. The molecular weight is calculated from the Periodic Table.

∙ 12y agoIn chemistry, a mole is a specific quantity of particles which could be either atoms or molecules, originally defined by Amadeo Avogadro as the quantity of air molecules that fit in a cubic meter of volume at standard temperature and pressure; we now consider it to be approximately 6.02 x 1023 of any given particle.

two moles in diatomic molecular elements. example hydrogen gas.
three moles in triatomic molecular elements. example ozone gas.
one mole in metals and other solids. examples copper, carbon, sulfur.
etc.
a mole of something is like a dozen of something, but many times more. a dozen is 12, a mole is roughly 6 * 1023.

∙ 11y agoThe molar mass of of any element in the periodic table is equal to its mass number. When there are isotopes of a particular element, the average value of all those according to the relative abundance is considered.

∙ 13y agoOne mole of any element has 6.02 x 1023 atoms of that element.
Ex: 1 mol of Oxygen is 16.00g, it has 6.02 x 1023 atoms of oxygen per mole.

A 1.0-mole sample of krypton gas has a mass of?
Since one mole is 6.02e23 of any atom, the atomic weight is equal to one mole of any element. For example, one mole of Ca is 40.08, one mole of S is 32.07. Thus being said, one mole of krypton is 83.80!
The molar mass of an element is the mass of one?
the mole of the element
How can a mole of any substance contain the same number of particles?
That's just the way it was set up. 6.022x1023 atoms of an element equals one mole of that element. 6.022x1023 molecules of a compound equals one mole of that compound. Remember, a mole does not measure weight. One mole of hydrogen weighs a lot less than a mole of acetic acid. A mole just means 6.022x1023 particles, whether those particles are atoms, ions, molecules, or ionic compounds.
Mass of 1 mol of oxygen atoms?
mass of one mole of oxygen atom is 16 grams. atomic weight of any atom is equal to mass of 1 mol of that atom...
What elements other than carbon have been used to define a mole?
Any element can me measured in molar quantities.One mole of any element has 6.02 x 10 23 atoms of that element.Hydrogen is the simplest element to use.
What is the mass of one mole of an element that has an atomic mass of 6.94?
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
A 1.0-mole sample of krypton gas has a mass of?
Since one mole is 6.02e23 of any atom, the atomic weight is equal to one mole of any element. For example, one mole of Ca is 40.08, one mole of S is 32.07. Thus being said, one mole of krypton is 83.80!
How many atoms are in 1 mole of 12c?
If you mean carbon-12, there are 6.022 x 1023 atoms in one mole. This is true of any element and any of its isotopes. Therefore, one mole of any element or a particular isotope is 6.022 x 1023 atoms.
The molar mass of an element is the mass of one?
the mole of the element
How much does one mole of 0 weigh?
1 mole of O (oxygen) weighs 15. 9996 grams. By definition, 1 mole of any element is equal to its atomic weight expressed in grams. 1 mole is equal to 6.02 x 1023 atoms of that element.
How does a mole of atoms of one element compare to a mole of another element?
Type your answer here...they all be equal to that element's atomic mass in grams.
If 32 grams of an element was equal to 1 mole of the element what is that element?
There are 32 grams of sulfur in a mole of that element. There are also 32 grams of oxygen in one mole of oxygen as it is found in its natural state (O2).
What is the approx mass of one mole of helium atoms?
4 grams. Approximately, mass (in grams) of 1 mole of any chemical element is just the atomic mass of this element (4 - for He, 12 - for C, and so on). It follows from the definition of one mole - number of atoms in 12 g of C.
How many atoms are in a mole of any element?
6.022x10 ^23
What is abogadro's number?
The number of atoms of any element in a mole of such.
What is the mass of one mole atom of sulfur?
32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.
What does the atomic mass of an element indicate?
The average weight in grams of one mole of the element.
