Question

Mass of one atom of oxygen is:

(a) 1/6.022 × 10^23
. g (b) 32/6.022 × 10^23 g (c) 16/6.022 × 10^23 g ​

Answer 1

Answer:

Atomic weight of oxygen=16g/mol

1 mol oxygen atom contains 6.023×10²³=16g

Mass of ⇒6.023×10²³oxygen atoms =16g

Mass of 1 atom of oxygen =16g÷6.023×10²³ =2.66×10−23g
