Answer:- The weight of the arrow is 0.75 ounces.
Solution:- It is a unit conversion problem where we are asked to convert grains to ounces. We could easily do this conversion using two steps conversion, grains to pounds and pounds to ounces.
We know that, 1 pound = 7000 grains
1 pound = 16 ounces
Let's make the set up to convert 330 grains to ounces as:
= 0.75 ounces
So, the weight of 330 grains of arrow in ounces is 0.75.

Answer:
Average atomic mass = 63.62 amu.
Explanation:
Abundance of Co⁶³ = 69.2%
Abundance of Co⁶⁵ = 30.8%
Atomic mass of Co⁶³ = 63 amu
Atomic mass of Co⁶⁵ = 65 amu
Average atomic mass = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (63×69.2)+(65×30.8) /100
Average atomic mass = 4359.6 + 2002 / 100
Average atomic mass = 6361.6 / 100
Average atomic mass = 63.62 amu.
