3.29 moles Zn x 6.02x10^23 atoms/mole = answer (do the math)
The number of atoms of nitrogen of 0,755 mol of N2 is 4,546716347035.10e23.
The number of atoms is 9,0332112855.10e23.
The number of carbon atoms which are present in 0,062 mol acetic acid HC2H3O2 is 0,747.10e23.
Firstly, you'll need to convert the grams into number of mols. Since no. of mol = mass/molecular weight 3.55/39.1 = 0.09079 mol because 1 mol of potassium consists of 6.02x10^23 atoms; 0.09079 mol of potassium will consist of 0.09079x(6.02x10^23)=5.466x10^22 atoms of potassium.
Since a mole of a metal is generally considered to be Avogadro's Number of atoms of the metal, the answer is 3.5 times Avogadro's Number or 2.1 X 1024 atoms, to the justified number of significant digits.
The number of atoms of nitrogen of 0,755 mol of N2 is 4,546716347035.10e23.
1.12 x 10^22 atoms PFirst determine the number of moles in the 0.577 g sample of phosphorus, determine the number of moles in the sample. Then multiply the moles by 6.022x10^23 atoms/mol.0.577 g P x (1 mol P/30.974 g P) x (6.022x10^23 atoms P/1 mol P) = 1.12 x 10^22 atoms P
To calculate the number of atoms in 13.2 mol of copper, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Multiply 13.2 mol by Avogadro's number to get the number of atoms: 13.2 mol * (6.022 x 10^23 atoms/mol) = 7.93 x 10^24 atoms. Therefore, there are approximately 7.93 x 10^24 atoms in 13.2 mol of copper.
The number of atoms in 0.40 mole of ANY element or compound is: 0.40 mol x 6.022x1023 atoms/mol = 2.4x1023 atoms.
To find the number of sulfur atoms in a given mass of sulfur, you can use the following steps: Determine the number of moles of sulfur using the formula: moles = mass molar mass moles= molar mass mass Given that the molar mass of sulfur ( S S) is 32.06 g/mol and the mass ( m m) is 1.56 g: moles = 1.56 g 32.06 g/mol moles= 32.06g/mol 1.56g Once you have the moles of sulfur, you can use Avogadro's number (6.022 x 1 0 23 10 23 mol − 1 −1 ) to find the number of atoms: number of atoms = moles × Avogadro’s number number of atoms=moles×Avogadro’s number Let's calculate it: moles = 1.56 g 32.06 g/mol ≈ 0.0488 mol moles= 32.06g/mol 1.56g ≈0.0488mol number of atoms = 0.0488 mol × ( 6.022 × 1 0 23 mol − 1 ) number of atoms=0.0488mol×(6.022×10 23 mol −1 ) number of atoms ≈ 0.0488 × 6.022 × 1 0 23 number of atoms≈0.0488×6.022×10 23 number of atoms ≈ 3.0 × 1 0 22 number of atoms≈3.0×10 22 Therefore, there are approximately 3.0 × 1 0 22 3.0×10 22 sulfur atoms in 1.56 g of sulfur.
Avagadro's number = 6.022 × 1023 atoms/mol0.5 mol × (6.022 × 1023) atoms/mol = 3.011 ×1023 atoms
The number of atoms is 9,0332112855.10e23.
The number of carbon atoms which are present in 0,062 mol acetic acid HC2H3O2 is 0,747.10e23.
b. 7.95 ´ 1024 atoms
To determine the molar mass for any compound, you multiply the molar mass of each element (atomic mass in grams) times its subscript, which represents the number of atoms of that element. Then add the result for each element. Molar Mass of P4S3 (4 atoms x 30.974g/mol P) + (3 atoms x 32.06g/mol S) = 123.90g/mol P + 96.18g/mol S = 220.08g/mol P4S3
Firstly, you'll need to convert the grams into number of mols. Since no. of mol = mass/molecular weight 3.55/39.1 = 0.09079 mol because 1 mol of potassium consists of 6.02x10^23 atoms; 0.09079 mol of potassium will consist of 0.09079x(6.02x10^23)=5.466x10^22 atoms of potassium.
The number of atoms is 39,746.10e23.
