Quite a few!
8.2 X 10^22 atoms of N2I6 (1 mole N2I6/6.022 X 10^23)(789.42 grams/1 mole N2I6)
= 107 grams of N2I6
(Would have been peanuts without all that iodine! )
divide the amount of particles given in the question by avagado's number to get the amount in moles. 3.01 x 1023 / 6.022 x 1023 which is about 0.5 moles. them multiply the amount of moles by the mass of Nitrogen to get it in grams. 0.5 x 14 = 7g
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
There are approximately 3.633 x 10^23 carbon atoms in 21.84 grams of carbon.
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).
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.
To calculate the number of grams in 4.1 x 10^22 molecules of N2I6, you first need to find the molar mass of N2I6. Then, use this molar mass to convert the number of molecules to grams using Avogadro's number and the formula: grams = (number of molecules) / (Avogadro's number) * molar mass.
The nitrogen iodide is NI3.
divide the amount of particles given in the question by avagado's number to get the amount in moles. 3.01 x 1023 / 6.022 x 1023 which is about 0.5 moles. them multiply the amount of moles by the mass of Nitrogen to get it in grams. 0.5 x 14 = 7g
To convert molecules to grams, you need to use the molar mass of the compound. For N2I6, the molar mass is 539.59 g/mol. First, calculate the number of moles in 8.2 x 10^22 molecules by dividing the number of molecules by Avogadro's number. Then, multiply the number of moles by the molar mass to find the grams.
To find the mass of 8.2 x 10²² atoms of N₂I₆, first determine the number of molecules, which is equal to the number of atoms divided by the number of atoms in one molecule of N₂I₆ (which contains 8 atoms). This gives approximately 1.025 x 10²² molecules. The molar mass of N₂I₆ is about 360.8 g/mol. Therefore, the mass in grams can be calculated by multiplying the number of molecules by the molar mass and dividing by Avogadro's number (6.022 x 10²³), resulting in approximately 57.4 grams.
1,25 grams of CH4 contain 0,156696.10e23 atoms.
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
3.05 x 1025
There are approximately 3.633 x 10^23 carbon atoms in 21.84 grams of carbon.
The answer is 47,128 x 1023 atoms.
