Question

find no. of gram atoms in 50 gram of oxygen
please answer it!!!!!!!!!!!!!!!!!

Answer 1

molecular weight of oxygen is 16*2 = 32

given mass of oxygen is 50gm

so no. of moles will be
= given mass/molecular mass

50/32 = 1.56mol

since one mole contain
6.023 * 10^23molecules

so 1.56 mol will contain

6.023*10^23 *1.56
9.4 * 10^23 molecules of oxygen

since one one molecule contain 2 oxygen atom

9.4 * 10^23 molecule will contain
9.4 * 10^23 *2
= 18.8 * 10^23 atoms.
