5 g of sulfur contain 0,94.10e23 atoms.
5.60 g C6H12O6 (1 mole C6H12O6/180.156 g)(6 moles C/1 mole C6H12O6)(6.022 X 1023/1 mole C) = 1.12 X 1023 atoms of carbon ======================
Statement C is not true. One mole of krypton atoms has a mass of approximately 83.798 g, not 41.90 g.
1 g hydrogen (H) has 6,022 140 857.10e23 atoms.
41,1 g of sodium sulfate (Na2SO4, anhydrous) contain 10,455.10e23 atoms.
169 g C x 1 mole C/12.011 g x 6.02x10^23 atoms/mole = 8.47x10^24 atoms
There are 7.16 moles of carbon in 85.9 g of carbon (85.9 g / 12 g/mol). Since there are 6.022 x 10^23 atoms in 1 mole of carbon, the number of carbon atoms in 85.9 g is 4.31 x 10^24 atoms.
To find the number of carbon atoms in 12 g of carbon (C), you first need to calculate the number of moles of carbon (C) in 12 g using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23) to determine the number of atoms in that many moles of carbon (C).
There are approximately 1.34 x 10^22 carbon atoms in 1.6 g of carbon. This calculation is based on the molar mass of carbon (12 g/mol) and Avogadro's number (6.022 x 10^23 atoms/mol). To find the number of atoms, divide the mass of the sample by the molar mass of carbon, and then multiply by Avogadro's number.
49.1740 g (6.02 x 1023 atoms) / (91.22 g) = 3.25 x 1023 atoms
To find the number of moles of atoms in a compound, first calculate the molar mass of the compound (12 g/mol for carbon, 1 g/mol for hydrogen). Then divide the given number of atoms by Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of moles. In this case, 5.21x10^24 atoms of C2H2 would be equivalent to approximately 8.65 moles.
There are 0.75 moles of carbon in 0.09 g. Since there is 1 mole of carbon contains 6.022 x 10^23 atoms, there are 4.52 x 10^22 atoms of carbon in 0.09 g.

There are 6.022 x 10^23 atoms in 1 mole of carbon. The molar mass of carbon is 12 g/mol. Therefore, in 72.0 g of carbon, there are (72.0 g / 12 g/mol) * 6.022 x 10^23 atoms = 3.61 x 10^24 atoms of carbon.
That is 1.975 ounces
To find the number of carbon atoms in 0.08 g of carbon, you need to calculate using Avogadro's number and the molar mass of carbon. The molar mass of carbon is approximately 12 g/mol. First, convert grams to moles by dividing 0.08 g by the molar mass of carbon to get approximately 0.0067 moles of carbon. Then, multiply the number of moles by Avogadro's number (6.022 x 10^23) to find that there are approximately 4 x 10^21 atoms of carbon in 0.08 g.
