How many hydrogen atoms are in 0.0542 mol of H2SO4? Answer in units of atoms H
To determine the number of hydrogen atoms in 0.0542 mol of H2SO4, you need to use Avogadro's constant (6.022 x 10^23 atoms/mol) and the stoichiometry of the compound.
The formula for sulfuric acid (H2SO4) tells us that there are 2 hydrogen atoms for each molecule of H2SO4. Therefore, in 1 mol of H2SO4, we have 2 mol of hydrogen atoms.
First, calculate the number of moles of hydrogen atoms in 0.0542 mol of H2SO4:
Number of moles of H atoms = 2 mol of H atoms/mol of H2SO4 × 0.0542 mol of H2SO4
= 0.1084 mol of H atoms
Next, convert the number of moles of hydrogen atoms to atoms:
Number of atoms of H = Number of moles of H atoms × Avogadro's constant
= 0.1084 mol of H atoms × 6.022 x 10^23 atoms/mol
≈ 6.524 x 10^22 atoms H
Therefore, there are approximately 6.524 x 10^22 hydrogen atoms in 0.0542 mol of H2SO4.
First, find out how many moles of hydrogen there are
Then, use Avagadro's Constant to find out how many atoms there are.
