How many moles of H2 gas are present in 6.0 L flask at stp?
The answer is 0,2675 moles.
How many atoms of hydrogen are in 16.2 l of h2 at stp?
Using stoichiometry, 16.2 L of H2 gas at STP equals about .7228 moles (1 L of gas at STP has a volume of 22.41 L), and there are 6.02 x 1023molecules of hydrogen in a mole, so we have (6.02 x 1023molecules/mol)(.7228 mol) = 4.35 x 1023 hydrogen molecules. There are two hydrogen atoms in each molecule, so the answer is (4.35 x 1023molecules H2)(2 H atoms/molecule) = 8.70 x 1023 H atoms in 16.2 L.

How many hydrogen molecules are in 31.8 L H2(g) at STP?
To find the number of hydrogen molecules, first calculate the number of moles in 31.8 L of H2 at STP using the ideal gas law. Then use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many atoms of hydrogen are in 67.2 l of h2 at stp?
At STP (Standard Temperature and Pressure), the volume of 1 mole of any gas is 22.4 liters. Since hydrogen gas exists as H2 molecules, 67.2 liters of hydrogen gas at STP contains 3 moles of H2 molecules. Since each H2 molecule contains 2 hydrogen atoms, there are 6 moles of hydrogen atoms, which is equivalent to 6 x 6.022 x 10^23 atoms 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
