Question

Problem 1.1 : Mass of an atom of oxygen in
gram is 26.56896 x 10-24 g. What is the atomic
mass of oxygen in u?​

Answer 1

Answer:

Answer: Given,

mass of the atom of Oxygen = 26.56896×10-24 g

number of atom = 1

using the formula

number of atom = mass/ atomic mass × avogadro's number

1 = 26.56896× 10-24 / At.mass×6.022×10^23

At.mass = 15.999828g

At.mass = 16g

Hope this helps you
