How many atoms of hydrogen are found in 2.48 mol of propane, C3H8?
Someone can explain to me. Thanks
How many molecules do you have in 2.48 moles C3H8? There are 6.022 x 10^23 molecules in 1 mol; therefore, there must be 2.48 x 6.022 x 10^23 molecules in 2.48 moles. That is 1.49 x 10^24 molecules. Then each molecule C3H8 has 8 H atoms so total number of H atoms must be 1.49 x 10^24 x 8 = ??. Check my arithmetic.
To determine the number of hydrogen atoms in 2.48 mol of propane (C3H8), you need to use the balanced chemical equation for the combustion of propane, which states that it contains three carbon atoms and eight hydrogen atoms.
From the equation, you can see that there are eight hydrogen atoms in one molecule of propane (C3H8). Therefore, to find the number of hydrogen atoms in 2.48 mol of propane, you need to multiply the number of moles by Avogadro's number.
Avogadro's number is 6.022 x 10^23, which is the number of particles (atoms, molecules, or ions) in one mole of a substance.
So, the calculation would look like this:
Number of hydrogen atoms = (2.48 mol) x (6.022 x 10^23 atoms/mol)
= 1.491 x 10^24 atoms
Therefore, there are approximately 1.491 x 10^24 atoms of hydrogen in 2.48 mol of propane (C3H8).
