how many atoms are there in 1.13 liters of hydrogen peroxide H2O2?
To determine the number of atoms in 1.13 liters of hydrogen peroxide (H2O2), you need to follow a series of steps:
Step 1: Convert liters to moles.
To convert from liters to moles, you need to use the ideal gas law constant, which is approximately 22.4 liters per mole at standard temperature and pressure (STP).
Number of moles = Volume (liters) / 22.4
For example, given 1.13 liters of H2O2:
Number of moles = 1.13 / 22.4
Step 2: Use Avogadro's number to convert moles to atoms.
Avogadro's number, approximately 6.022 × 10^23, represents the number of particles (atoms, molecules, or ions) in 1 mole of a substance.
Number of atoms = Number of moles × Avogadro's number
For example, if you calculate 1.13 liters of H2O2 to be 0.0504 moles:
Number of atoms = 0.0504 × 6.022 × 10^23
Therefore, in 1.13 liters of hydrogen peroxide (H2O2), there would be approximately 3.032 × 10^22 atoms.
