The number of grams in a mole of atoms depends on the element in question. A mole of any substance contains approximately (6.022 \times 10^{23}) entities, known as Avogadro's number. The mass in grams of one mole of atoms is equal to the Atomic Mass of the element, expressed in grams per mole (g/mol) on the Periodic Table. For example, one mole of carbon, with an atomic mass of about 12.01 g/mol, weighs approximately 12.01 grams.
17 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 8.5 X 1023 atoms of carbon =====================
To obtain one mole of iron atoms, you need to weigh out approximately 55.85 grams of iron. This is because the molar mass of iron (Fe) is about 55.85 grams per mole. Therefore, for one mole, you simply measure out this amount in grams.
10 grams nitrogen (1 mole N/14.01 grams)(6.022 X 1023/1 mole N) = 4.3 X 1023 atoms of nitrogen ======================
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.
Quite a few! 871 grams water (1 mole H2O/18.016 grams)(2 moles H/1 mole H2O)(6.022 X 1023/1 mole H) = 5.82 X 1025 atoms of hydrogen ========================
2.3 X 1024 atoms / 6.022 X 1023 atoms/mole X 107.87 gm/mole of silver = 412 grams
17 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 8.5 X 1023 atoms of carbon =====================
To obtain one mole of iron atoms, you need to weigh out approximately 55.85 grams of iron. This is because the molar mass of iron (Fe) is about 55.85 grams per mole. Therefore, for one mole, you simply measure out this amount in grams.
31.8 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C)= 1.59 X 1024 atoms of carbon===================
There are about 6.02 x 10^23 atoms in 16.3 grams of sulfur, which is Avogadro's number representing one mole of atoms or molecules. This is known as a mole, where one mole of any element contains Avogadro's number of atoms.
The molar mass of sulfur is approximately 32 grams per mole. Therefore, 100 grams of sulfur would contain approximately 3 moles of sulfur atoms (100 grams / 32 grams/mole). To find the number of atoms, you would then multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms/mole) to get the total number of sulfur atoms in 100 grams.
There are approximately 1.93 x 10^23 atoms in 300 grams of gold. This is calculated using Avogadro's number (6.022 x 10^23 atoms/mole) and the molar mass of gold (197 grams/mole).
