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.
How is a mole related to the atomic mass?
The atomic mass, in grams, is the mass of one mole of atoms.
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 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.
What has a greater mass one mole of silver or one mole of gold?
Gold
Molar mass is a?
The mass of one mole of substances
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 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.
What is the mass in grams of one mole of sulfur dioxide SO2?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the atomic mass. Sulfur's atomic mass is 32.064 grams.
How many mass of a substance a mole contains?
One mole contain the molar mass of a compound, expressed in grams.
What is the mass of one mole of silicon carbide?
The molar mass of silicon carbide (SiC) is approximately 40.1 g/mol for silicon and 12.0 g/mol for carbon, giving a total molar mass of about 52.1 g/mol. Therefore, the mass of one mole of silicon carbide is approximately 52.1 grams.
What does one mole of carbon have a mass of?
12g
Does one mole of krypton atoms has a mass of 41.90g?
No, the molar mass of krypton (Kr) is approximately 83.80 g/mol, so one mole of krypton atoms would have a mass of 83.80 grams.
