The number of N atoms in 681 g of C7H5N3O6is x × 1021. The value...
To find the number of N atoms in C7H5N3O6, we need to first find the molar mass of the compound:
C = 12.01 g/mol
H = 1.01 g/mol
N = 14.01 g/mol
O = 16.00 g/mol
Molar mass of C7H5N3O6 = (7 x 12.01) + (5 x 1.01) + (3 x 14.01) + (6 x 16.00) = 269.25 g/mol
Next, we need to find the number of moles of C7H5N3O6:
Number of moles = Mass / Molar mass = 681 g / 269.25 g/mol = 2.53 moles
Finally, we can use the chemical formula to find the number of N atoms:
Number of N atoms = 2.53 moles x 3 atoms of N per molecule = 7.59 atoms of N
Therefore, the number of N atoms in 681 g of C7H5N3O6 is approximately 7.59.
C = 12.01 g/mol
H = 1.01 g/mol
N = 14.01 g/mol
O = 16.00 g/mol
Molar mass of C7H5N3O6 = (7 x 12.01) + (5 x 1.01) + (3 x 14.01) + (6 x 16.00) = 269.25 g/mol
Next, we need to find the number of moles of C7H5N3O6:
Number of moles = Mass / Molar mass = 681 g / 269.25 g/mol = 2.53 moles
Finally, we can use the chemical formula to find the number of N atoms:
Number of N atoms = 2.53 moles x 3 atoms of N per molecule = 7.59 atoms of N
Therefore, the number of N atoms in 681 g of C7H5N3O6 is approximately 7.59.

The number of N atoms in 681 g of C7H5N3O6is x × 1021. The value...
M.M. of C7H5N3O6 = 84 + 5 + 42 + 96 = 227
nN = 681/227 × 3 = 9 mol
Number of N atoms = 9 × 6.02 × 1023
= 5,418 × 1021
The answer is 5,418.
nN = 681/227 × 3 = 9 mol
Number of N atoms = 9 × 6.02 × 1023
= 5,418 × 1021
∴
