Question

what will be the mass of an atom of potassium if there are 94 atoms of k=39 6atom of k=41​

Answer 1

case I

when atomic mass of an potassium(k) atom=41u

we have to find mass of 94 atoms=no. of atoms given × mass of an atom

94×41

3854u

case II

when atomic mass of an potassium(k) atom=39u

we have to find mass of 6 atoms=no. of atoms given × mass of an atom

6×39

234u

dude your question is wrong because you already give atomic mass in the question.But I find the maas of all the atoms .Check the question and send to me again
