What is the mass of one mole atoms?
The mass depends on the element whose atoms are concerned. For eg, 1 mol Helium atoms have mass 4 g 1 mol Neon atoms have mass 20 g.
What is the mass of one mole of sodium atom?
HI, A MOLE IS MOLECULAR MASS. MOLECULAR MASS OF SODIUM IS 23. HENCE, 1.22 MOLE = 1.22*23 = 28.60
What is the total mass of oxygen 1.00 mole of AI2CrO43?
In this molecule, there are 4 oxygen atoms, so 1 mole of this substance would have 4 moles of oxygen atoms. Each oxygen atom is 16 g/mole, so 64 grams.
How many atoms are in 5.0 mole of Fe?
Fe, or iron, has a molar mass of 55.845 grams per mole. This means that 0.2 moles is equal to 11.2 grams of iron.
How many atoms does sodium have if it has 23.0 g?
Number of particles (atoms) =Avogadro's number (parts per mole) * [ mass (grams) / molar mass (grams per mole) ]So: N = 6.02*10+23 * 23.0 / 22.99 = 6.02*10+23atoms sodium
What is the mass of 9.46E plus 23 atoms of krypton?
I think you do not need the " plus. " 9.46 X 10^23 atoms Krypton (1 mole Kr/6.022 X 10^23)(83.80 grams/1 mole Kr) = 132 grams of Krypton ---------------------------------
If 6.02 x 1023 atoms of element y have a mass of 83.80 g what is the identity of y?
6.02 x 1023 atoms of an element is one mole of that element. The mole, based on Avagadro's number, is defined as the number of Carbon atoms that would have a mass of 12 grams. This is a scaling factor related to atomic mass. Krypton has an atomic mass of 83.8, so if a mole of an unknown element is 83.8 grams, then that element is Krypton.
What statement about krypton is not true A its molar mass is 83.798 g per mol Kr B Its atomic number is 36 C one mole of krypton atoms has a mass of 41 point 90g D it is a noble gas?
C is not correct.
Which would have a higher mass a mole of K atoms or a mole of Au atoms?
A mole of Au
Does mole of carbon atoms have a different mass than a mole of sulphur atoms?
Yes. To find out the mass of a mole of atoms of any given element, see the atomic mass given on the periodic table. A mole of carbon atoms has a mass of 12.011 grams. A mole of sulfur atoms has a mass of 32.06 grams.
What is the relationship between an Atoms mass and one mole of that atom?
If the Atomic Mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
What would have the greatest mass 1 mole of iron atoms 2 moles of oxygen atoms 4 moles of carbon atoms or 1 mole of potassium atoms?
1 mole of iron atoms has the greatest mass - 55,845 g.
What is 84 in Krypton-84?
The 84 is the number of protons and neutrons (nucleons) in the atomic nucleus of the isotope krypton-84. . As Kr has an atomic number of 36, the number of protons is 36, and in krypton -84 there are therefore 48 neutrons.
What is the difference between the mass of a mole of oxygen and a mole of O2 molecules?
A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.
Why does a mole of copper atoms weigh less than a mole of lead atoms?
Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
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!
Is it true the size of a mole of atoms has a reasonable mass?
is it true the size of a mmole of atoms has a reasonable mass
