First, 2C6H8O7 is NOT an element it is a Compound.
Second the formula for the compound TELLS you how many atoms are present!
2C6H8O7 = Ignoring the element symbols is 2*(6+8+7)
2*(6+8+7)= 2*(21) = 42 Atoms
Multiply the coefficient times the subscript for each element. For 3Na2SO4, there are a total of 6 sodium atoms, 3 sulfur atoms, and 12 oxygen atoms.
Mg(NO3)2 is magnesium nitrate and it is not an element, but is a compound. Each molecule has 1 Mg atom + 2 N atoms + 6 O atoms for a total of 9 atoms per molecule. The more molecules you have, the more atoms you have.
This depends on the mass of this element.
1 mol of any chemical element has 6,022 140 857.10e23 atoms.
Ununseptium is a chemical element formed from atoms and doesn't contain inside atoms.
C8H12 8 Carbon atoms + 12 Hydrogen atoms = 20 atoms total
Multiply the coefficient times the subscript for each element. For 3Na2SO4, there are a total of 6 sodium atoms, 3 sulfur atoms, and 12 oxygen atoms.
There are 21 atoms, because there are 9 atoms of Carbon 8 atoms of Hydrogen and 4 atoms of Oxygen.
There are no "atoms in an element," but rather atoms OF an element. If you are trying to find the number of atoms in a sample of a pure element you divide its weight by its molar mass and then multiply by 6.022 x 10^23 to get the answer in atoms. The answer options are 2,3, or 4.
Mg(NO3)2 is magnesium nitrate and it is not an element, but is a compound. Each molecule has 1 Mg atom + 2 N atoms + 6 O atoms for a total of 9 atoms per molecule. The more molecules you have, the more atoms you have.
This depends on the mass of this element.
Gold is the element gold no matter how many atoms of it you have.
many identical atoms Answer is= Atoms.
1 mol of any chemical element has 6,022 140 857.10e23 atoms.
C6H12O6. Six carbon atoms, 12 hydrogen atoms and six oxygen atoms.
Multiply 8.7 by avagadros number to get the number of molecules. 8.7x6.02x1023=5.24x1024 molecules of NO. as there is 1 atom of N and one of O for each molecule there are 5.24x1024 atoms of each element. this means that the total number of atoms is 2x5.24x1024 = 1.05x1025 atoms
Rutherfordium is a single chemical element.
