How many molecules of H2(g) are there in a 21.25 gram sample?
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.
How many atoms in 1g H2?
1 gram H2 (1 mole H2/2.016 grams)(6.022 X 1023/1 mole H2) = 3 X 1023 atoms of hydrogen gas =========================
Which is diffused most readily lpg CO2 h2 n2?
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.
How many hudrogen molecule are there in 10grams of hydrogen?
1 mole H2 = 2.016g H2 = 6.022 x 1023 molecules H210g H2 x 1mol H2/2.016g H2 x 6.022 x 1023 molecules H2/1mol H2 = 3 x 1024 molecules H2 (rounded to 1 significant figure)

Which is diffused most readily lpg CO2 h2 n2?
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.
Which gas from among CO2 CH4 H2 will diffuse the fastest and why give the reason?
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.

What is the no of molecules of H2 and CO2 with the same volume?
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.
What are the monomers for oxygen hydrogen nitrigen carbon dioxide?
The monomers for these molecules are as follows: Oxygen: O2 Hydrogen: H2 Nitrogen: N2 Carbon dioxide: CO2
What is the product of H2?
The product of H2 is hydrogen gas (H2) composed of diatomic molecules.
Are the gaseous di-atomic molecules of the Elements different from the molecules of Compounds?
Yes. The diatomic molecules of the elements include primarily H2, N2 & O2; Examples of molecular compounds include: H2O, C2H5OH, NH3, CO2, DNA and sugar.
In the equation 2 H2 plus O2 the H2 molecules are?
H is the atomic symbol for hydrogen, the 2 subscript means it is diatomic.
