Answer 1

Answer:

55.84

Explanation:

the formula to solve this particular question is

avg atomic mass=m1*p1+m2*p2+.........

Answer 2

Answer:

Hello friends,

Just you have to multiply with masses * the abundance %

Explanation:

We know that fe 54 & fe 55 with 90% and 5%.

54*90/100+55*5/100

=48.6+2.75

=51.35%

Therefore the abundance %of fe 54 & fe 55 is 51.35%

Thank you...
