Since a hydrogen atom consists of one proton and one electron, it should have a mass of 1.763 x 10^-24 grams. Using unit factoring, calculate how may hydrogen atoms you'd have if you had 5.6 g of hydrogen.
Thank you!
1.763E-24 g/e x #e = 5.6g
could you clarify what you mean by this answer? I was confused. Thank you! :)
To calculate the number of hydrogen atoms in 5.6 grams of hydrogen, you need to use the molar mass of hydrogen to convert grams to moles, and then use Avogadro's number to convert moles to atoms.
1. Start by calculating the number of moles of hydrogen in 5.6 grams using the molar mass of hydrogen. The molar mass of hydrogen is approximately 1.008 grams per mole.
5.6 g hydrogen × (1 mol hydrogen / 1.008 g hydrogen) = 5.555 mol hydrogen (rounded to three decimal places)
2. Next, use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole, to convert moles of hydrogen to atoms.
5.555 mol hydrogen × (6.022 x 10^23 atoms / 1 mol) = 3.34 x 10^24 hydrogen atoms (rounded to three significant figures)
Therefore, if you had 5.6 grams of hydrogen, you would have approximately 3.34 x 10^24 hydrogen atoms.
