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?
There are approximately 3.01 x 10^22 atoms in 1 gram of H2 molecules.
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?
There are approximately 1340 molecules of hydrogen in 10 grams of hydrogen.
How many moles of hydrogen gas contained in 9.03x1023?
Given/Known:1mole of H2 = 2.01588g H21mole of H2 = 6.022 x 1023 molecules H21) Convert molecules of H2 to moles of H2 by doing the following calculation.9.4 x 1025 molecules H2 x (1mol H2/6.022 x 1023 molecules H2) = 156mol H22) Convert the moles of H2 to mass in grams of H2.156mol H2 x (2.01588g H2/1mol H2) = 314g H2
What molecules is the heaviest CO2 H2O co or h2?
CO2

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
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?
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.
What happen when water gas heated under pressure in the presence of Zn O - Cr O?
Water gas is a mixture of CO and H2 and H2O. Over oxide catalysts the "water gas shift" reaction occurs that removes the CO by reacting it with water to produce CO2 and more H2. CO + H2O -> CO2 + H2
How many molecules of H2 are required to completely react with six molecules of N2?
Three molecules of H2 are required to completely react with six molecules of N2 to form ammonia (NH3) according to the balanced chemical equation: N2 + 3H2 → 2NH3.
