Question

calculate number of electron proton and neutron of 48 gram of oxygen atom​

Answer 1

Hi there,

♤ Given:

• Oxygen sample mass (ms) is 48 gm

• Oxygen atomic mass (Mwt) is 16g/mol

• NA = avogadro's number = 6.02×10^23

• Oxygen atomic structure is

• 8electrons

• 8Protons

• 8Neutrons

~~~~~~~~~~~

◇ Calculate number of moles by dividing sample mass (ms) over the atomic mass (Mwt)

■ n = ms ÷ Mwt = 48÷16 = 3 mols

◇ Calculate number of atoms by multiple the moles by avogaro's number

■ Nu = n× NA = 3×6.02×10^23 = 1.8×10^24 atom

◇ Each atom have 8 units from each partical so,

☆ Number of electrons = 8×1.8×10^24

And same for protons , neutrons
