CO2
Wiki User
∙ 12y agoA gram of CO2 has more molecules than a gram of H2 because CO2 has more atoms per molecule (three atoms in CO2 compared to two in H2). Thus, CO2 will have a higher total number of molecules per gram.
To calculate the number of molecules, you first need to determine the number of moles of H2 in the 21.25 gram sample using the molar mass of H2 (2 grams/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
There are approximately 3.01 x 10^22 atoms in 1 gram of H2 molecules.
CO2 and H2 will diffuse more readily than LPG (liquefied petroleum gas) and N2 (nitrogen) due to their smaller molecular sizes. Smaller molecules move more quickly and can diffuse through barriers more easily.
There are approximately 1340 molecules of hydrogen in 10 grams of hydrogen.

Hydrogen (H2) will diffuse the fastest because it has the smallest molecular weight, which corresponds to higher average speeds of the gas particles at a given temperature. This allows hydrogen molecules to move more quickly through a medium compared to the heavier carbon dioxide (CO2) and methane (CH4) molecules.

The molar volume at 1 bar and 0 0C is 22,710 980(38) L/mol; each mol contain 6,022 140 857.10e23 molecules.
The monomers for these molecules are as follows: Oxygen: O2 Hydrogen: H2 Nitrogen: N2 Carbon dioxide: CO2
Yes. The diatomic molecules of the elements include primarily H2, N2 & O2; Examples of molecular compounds include: H2O, C2H5OH, NH3, CO2, DNA and sugar.
The product of H2 is hydrogen gas (H2) composed of diatomic molecules.
In the equation 2 H2 + O2, the H2 molecules are reactants that will participate in the reaction. They will combine with the O2 molecules to form water (H2O) molecules in the chemical reaction.
