Question

What is mass in gram of 6.022×10^28 atoms of sodium

Answer 1

This means that a single atom of sodium weighs 23 atomic mass units (AMUs), but it also means that one mole of sodium atoms weighs 23 grams. Hence 6.02 x 10^23 atoms of sodium weight a total of 23 grams.

Answer 2

Number of moles=number of particles/avogado's number

6.022×10^28 /6.022*10^23

=10^5

Number of moles=given mass /molar mass

10^5=g/23

g=10^5*23 OR

2300000 gram is your answer

mark me as brainliest as i am dam sure my answer is correct one.please.
