Question

Hydrolamine ,NH2OH , is a reducing agent found in some film developing solutions. How many hydrogen atoms are in 1.80moles of hydroxylamine?

Answer 1

There are 3.24 × 1024 hydrogen atoms in 1.80 moles of hydroxylamine, calculated by multiplying the number of moles by the number of hydrogen atoms in each molecule (3) and then by Avogadro's number.

Step-by-step explanation:

Hydroxylamine, or NH2OH, is a compound that consists of one nitrogen atom, two oxygen atoms, and three hydrogen atoms. In regards to the question, to calculate how many hydrogen atoms are in 1.80 moles of hydroxylamine, we should consider the molecular formula of hydroxylamine which shows three hydrogen atoms per molecule.

To find the total number of hydrogen atoms in 1.80 moles of hydroxylamine, we can apply Avogadro's number (6.022 × 1023 atoms per mole). The calculation is as follows:

1. Identify the number of hydrogen atoms per molecule of hydroxylamine: 3 hydrogen atoms.
2. Multiply the number of moles by Avogadro's number to find the number of atoms in 1.80 moles.
3. The calculation will be: 1.80 moles × 3 hydrogen atoms/molecule × 6.022 × 1023 atoms/mole.
4. The result gives us: 1.80 × 3 × 6.022 × 1023 = 3.24 × 1024 hydrogen atoms.

Therefore, there are 3.24 × 1024 hydrogen atoms in 1.80 moles of hydroxylamine.

Answer 2

number of hydrogen atom in 1.8 mole of NH2OH =
`9.8* 10^(22)`

Step-by-step explanation:

percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule

=
`(3* 1)/(14+3+16)`\times 100

= 9.09 percentage

therefore number of moles in 1.8 moles of hydroxy amine =
`(9.09)/(100)* 1.8`

= .16 moles of hydrogen

number of hydrogen atom = (number of moles )×(avagadro number)

=
`9.8* 10^(22)` atoms of hydrogen
