Question

calculate average atomic mass of oxygen​

Answer 1

Answer:

O-16=MASS=16

        ABUNDANCE=99.7%

O-17=MASS=17

        ABUNDANCE=0.04%

O-18=MASS=18

       ABUNDANCE=0.20%

AVERAGE ATOMIC MASS

= (16)(99.7)+(17)(0.04)+(18)(0.20)\100

=16.00

THEREFORE, AVERAGE ATOMIC MASS OF OXYGEN=16
