A hydrogen atom has a mass of
1.673x10^-24 g
How many hydrogen atoms would you have in 5.6 g of hydrogen?
1.673E-24 g/atom x # atoms = 5.6g
Solve for # atoms.
To find the number of hydrogen atoms in 5.6 g of hydrogen, we need to use Avogadro's number and the molar mass of hydrogen.
1. Determine the molar mass of hydrogen:
The molar mass of hydrogen (H) is approximately 1 g/mol.
2. Calculate the number of moles of hydrogen:
Moles = mass / molar mass
Moles = 5.6 g / 1 g/mol
Moles = 5.6 mol
3. Use Avogadro's number to find the number of atoms:
Avogadro's number (NA) is approximately 6.022 x 10^23 atoms/mol.
Number of atoms = Moles x NA
Number of atoms = 5.6 mol x 6.022 x 10^23 atoms/mol
Therefore, you would have approximately 3.37 x 10^24 hydrogen atoms in 5.6 g of hydrogen.
To find the number of hydrogen atoms in 5.6 grams of hydrogen, you need to use the concept of molar mass and Avogadro's number.
1. Start by calculating the molar mass of hydrogen (H). The molar mass is the mass of one mole (6.022x10^23 particles) of a substance. The molar mass of hydrogen is approximately 1.008 grams per mole.
2. Next, determine the number of moles of hydrogen in 5.6 grams. This can be done by dividing the mass of hydrogen by the molar mass of hydrogen:
Moles of hydrogen = Mass of hydrogen / Molar mass of hydrogen
Moles of hydrogen = 5.6 g / 1.008 g/mol
3. Calculate the number of hydrogen atoms in 5.6 grams of hydrogen using Avogadro's number. Avogadro's number is a constant equal to 6.022x10^23 particles per mole.
Number of hydrogen atoms = Moles of hydrogen * Avogadro's number
Number of hydrogen atoms = Moles of hydrogen * 6.022x10^23
4. Substitute the value calculated in step 2 into the equation from step 3 to find the number of hydrogen atoms in 5.6 grams of hydrogen.
Note: The molar mass and Avogadro's number used in the calculations are approximate values and should give you a reasonable estimation of the number of hydrogen atoms.
With the values given, the approximate number of hydrogen atoms in 5.6 grams of hydrogen can be calculated as follows:
Molar mass of hydrogen = 1.008 g/mol
Moles of hydrogen = 5.6 g / 1.008 g/mol = 5.56 mol
Number of hydrogen atoms = 5.56 mol * 6.022x10^23 atom/mol ≈ 3.35x10^24 hydrogen atoms
Therefore, there would be approximately 3.35x10^24 hydrogen atoms in 5.6 grams of hydrogen.
