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.)
What has more mass one mole of helium or one mole of lead?
Lead. The molar mass of lead is 207.2 g/mol while helium's is 4.0 g/mol.
The atomic mass of a mole?
The atomic mass of a mole is equal to the molar mass of that element expressed in grams. It represents the average mass of one mole of atoms of a particular element.
How many mass of a substance a mole contains?
One mole contain the molar mass of a compound, expressed in grams.
What is the atomic mass of arsenic?
The atomic mass of arsenic is approximately 74.92 atomic mass units.
how many arsenic atoms are there?
There are typically 6.022 x 10^23 atoms of arsenic in one mole of arsenic. This value is known as Avogadro's number and represents the number of atoms or molecules in one mole of a substance.
The mass of one mole of substance called its?
chicken nuggets
Which has a greater mass.. one mole of silver or one mole of gold?
One mole of gold has a greater mass than one mole of silver because gold has a higher atomic mass compared to silver. The atomic mass of gold is around 197 grams per mole, whereas the atomic mass of silver is around 108 grams per mole.
What is the mass of one mole?
The mass of one mole of a substance is equal to its molar mass, which is numerically equivalent to the atomic or molecular weight in grams. For example, one mole of carbon has a mass of 12 grams, one mole of water (H2O) has a mass of 18 grams, and one mole of sodium chloride (NaCl) has a mass of 58.5 grams.
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 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.)
What has a greater mass one mole of silver or one mole of gold?
Gold
What is mass number of arsenic?
The mass number of arsenic is 75, as it is the sum of the number of protons and neutrons in the nucleus of an arsenic atom.
Molar mass is a?
The mass of one mole of substances
What is the mass 1 mole of carbon?
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.
What is the mass of one mole of sodium atom?
The mass of one mole of sodium atoms is approximately 22.99 grams. This is calculated by adding up the individual atomic masses of the constituent atoms in one mole of sodium.
What is the mass of one mole atom of sulfur?
The molar mass of sulfur is approximately 32.06 grams/mol. Therefore, the mass of one mole of sulfur atoms is 32.06 grams.
