the density of Na2Co3 is about 2.54 g/cm3. so, the mass of it would be about 2.54*20=50.8 g.
50.4 divided 6.23*1023 equals to 8.08*10-23 mol
2.0 moles H2SO4 (6.022 X 1023/1 mole H2SO4)
= 1.2 X 1024 atoms of sulfuric acid
--------------------------------------------
Depending on the concentration of sulfuric acid.
Five molecules of H2SO4 contains 20 atoms of Oxygen
20 moles x 6.02x10^23 atoms/mole = 1.2x10^25 atoms
Since there are 10 water molecules with this species there are 20 atoms of H.
The chemical formula of propane is C3H8; 11 atoms are present in the molecule.
The molecular formula C6H8O6 contain 20 atoms.
The answer is o,1 mol.
The answer is 0,08 mol.
Five molecules of H2SO4 contains 20 atoms of Oxygen
To determine the total number of atoms and molecules in 5H2SO4, we first need to break down the chemical formula of sulfuric acid (H2SO4): 1 molecule of H2SO4 contains: 2 atoms of hydrogen (H) 1 atom of sulfur (S) 4 atoms of oxygen (O) Therefore, in 5 molecules of H2SO4, we have: 5 x 2 atoms of hydrogen = 10 hydrogen atoms 5 x 1 atom of sulfur = 5 sulfur atoms 5 x 4 atoms of oxygen = 20 oxygen atoms So, in total, there are 10 hydrogen atoms, 5 sulfur atoms, and 20 oxygen atoms in 5 molecules of H2SO4. Additionally, to find the total number of molecules in 5H2SO4, we simply multiply the coefficient (5) by the number of molecules in the formula (1 H2SO4 molecule) to get: 5 x 1 = 5 molecules of H2SO4. Therefore, in 5H2SO4, there are: 10 hydrogen atoms 5 sulfur atoms 20 oxygen atoms 5 molecules of H2SO4.
equation: g= 175 atoms x 1 mol/6.02x10^23 x 196.97g/1 mol ---> 175 atoms of gold weigh 5.73x10^-20 grams.
20 g NaOH is equivalent to 20(g) /[23+16+1](g/mol) = 0.5 mol NaOHThis will react with 0.5 mol H+ which is present in 0.25 mol H2SO4For this you'll need 0.25(mol) /2.0(mol/L) = 0.125 L = 125 mL of 2.0 M H2SO4-solution.
The mass depends on the element whose atoms are concerned. For eg, 1 mol Helium atoms have mass 4 g 1 mol Neon atoms have mass 20 g.
You would first need to know the mass of the soda cap. This is how you would do it.... the mass multiplied by 1 mol/the molar mass multiplied by 6.02x1023 . Then you would be left with the about of atoms.
The atomic weight of silver is 107,8682 g/molTo convert grams to moles:moles Ag=35,5 g Ag1 mol= 0,329 mol Ag107,8682 g
5x10-3 g divided by m.wt. of gold (197 g/mol) equals 2.5x10-5 mol gold.2.5x10-5 mol gold multiplied by Avogadro's Number (6.023x10+23 atoms/mol) equals 1.5x10+20 atoms.
Each mole of particles have 6.02 x 10^23 particles. (3.6 x 10^20) / (6.02 x 10^23) = 0.000598 mol of Silicon Ar of Si (Silicon) = 28.1g/mol mass = number of moles x Ar mass = 0.000598 mol x 28.1g/mol = 0.0168g of silicon
