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
Five molecules of H2SO4 contains 20 atoms of Oxygen
20 moles x 6.02x10^23 atoms/mole = 1.2x10^25 atoms
To calculate the number of atoms in 30.5 mg of copper wire, we first need to determine the number of moles of copper using its molar mass (63.55 g/mol). Then, we use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of copper to atoms.
What kind of formula is that? You are saying, two carbons, one oxygen, twenty four hydrogen atoms and then two more oxygen atoms. C2H24O3 ?????? Remember, you asked for it, but you can follow this general form. 0.383 mg C2OH24O2 (1 gram/1000 mg)(1 mole C2OH24O2/96.212 grams)(2 mole C/1 mole C2OH24O2)(6.022 X 10^23/1 mole C) = 4.79 X 10^18 atoms of carbon in that weird formula ------------------------------------------------------------------------
The chemical formula of propane is C3H8; 11 atoms are present in the molecule.

To find the moles of H2SO4 in a 20 ml of 4M solution, use the formula: Moles = Molarity x Volume (in liters). First, convert 20 ml to liters (20 ml = 0.02 L). Then, multiply the molarity (4 mol/L) by the volume (0.02 L) to find the moles of H2SO4, which is 0.08 moles.
To find the number of moles in the sample of H2SO4, we need to divide the given mass by its molar mass. The molar mass of sulfuric acid (H2SO4) is 98.08 g/mol. Therefore, 9.8g / 98.08 g/mol = 0.1 moles of H2SO4.
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.
To find the number of moles of H2SO4 in 20 ml of 4 M solution, we first need to calculate the number of moles present in 20 ml of the solution using the formula: moles = Molarity x Volume (L). Converting 20 ml to liters (20 ml = 0.02 L) and then calculating moles: 4 M x 0.02 L = 0.08 moles of H2SO4.
To find the number of calcium atoms in 179g of calcium, first calculate the molar mass of calcium which is approximately 40.08 g/mol. Next, divide the given mass by the molar mass to get the number of moles (179g / 40.08 g/mol ≈ 4.47 moles). Finally, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms (4.47 moles * 6.022 x 10^23 atoms/mol ≈ 2.69 x 10^24 atoms). Therefore, there are approximately 2.69 x 10^24 atoms in 179g of calcium.
The molar mass of copper is approximately 63.5 g. To find how many of these are in our sample we must divide.0.0159/63.5 = 2.5 x 10 ^ -4 = 0.00025 moles. Each mole contains the Avogadro number of atoms, i.e. 6.023 x 10 ^ 23, so in total we have 0.00025x 6.023 x 10 ^ 23 = 1.51 x 10 ^ 20 atoms approximately.
1mol Na in grams = 22.989770g 1mol Na atoms = 6.022 x 1023 atoms 1 x 1020 atoms Na x 1mol/6.022 x 1023 atoms x 22.989770g/mol = 0.004g Na (rounded to one significant figure)
To determine the number of gold atoms in the sample, you can use the molar mass of gold (197 g/mol) to first find moles, then convert moles to atoms using Avogadro's number (6.022 x 10^23 atoms/mol). First, find moles: 5.00 x 10^-3 g ÷ 197 g/mol = 2.54 x 10^-5 mol. Then, convert moles to atoms: 2.54 x 10^-5 mol x 6.022 x 10^23 atoms/mol = 1.53 x 10^19 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
Non!!!! They are two different substances/acids. The formulas for sulphuric acid is H2SO4 and for hydrochloric acid (HCl). With the exception of the hydrogens all the other elements present in the two difference acids are different.
The questions asks how many moles of carbon atoms.Molar mass is defined as the mass of one mole of a substance or in this case 6.022x1023 atoms of carbon. So the molar mass for carbon is 12.0 g/mol. Therefore the number of moles of carbon atoms is just 36/12.0 = 3.0 moles of carbon.How many atoms are in 36 grams of Carbon?[36 (gC) /12.0 (gC/molC)] * 6.02*10+23 (atoms C/molC) = 1.8*10+24 atoms in 36 g Carbon
