12 molecules of carbon
24 of hydrogen
12 of oxygen
To answer this kind of question, multiply the coefficient, 2, by the subscript after the atomic symbol for hydrogen, H, to obtain 24 hydrogen atoms.
To find the number of molecules in 42.0g of Cl2, you first need to determine the number of moles using the molar mass of Cl2 (71 g/mol). Next, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. Therefore, in 42.0g of Cl2, there would be approximately 3.56 x 10^23 molecules.
0.175 X Avogadro's Number = about 1.05 X 1023.
The number of bromine molecules present in the flask can be calculated using Avogadro's number, which is 6.022 x 10^23 molecules/mol. In this case, there are 0.380 mol of bromine, so the number of bromine molecules present is 0.380 mol x 6.022 x 10^23 molecules/mol.
To find the number of moles in 1.21 molecules of HBr, divide the number of molecules by Avogadro's number (6.022 x 10^23 molecules/mol). Thus, 1.21 molecules of HBr is approximately 2.01 x 10^-24 moles.
6 molecules of water
The answer is 0,166.10e23 molecules.
0,34 g HCl contain 5,6.10e21 molecules.

No, a vacuum by definition is a space with no air molecules present. Therefore, there are no air molecules inside a vacuum.
1,125 moles of sodium sulfate contain 6,774908464125.10e23 molecules.
Five molecules of propane have 40 hydrogen atoms.
there are 2 atoms of hydrogen in water
Your source is incorrect, it is impossible to make this a structural formula. You may mean C6H12O6 (glucose). I had a booklet with C2H12O6 as a spelling error.
There are 1.28x10^24 molecules of SF4. 2.13 mol * 6.022x10^23 molecules/mol = 1.28x10^24 molecules.
Five molecules of hydrogen have 10 atoms.
