Answer :
1. There are 4.85 dozens of apples are there in a 5.000 lbs (2268 g) bag.
(1 dozen of apples =2112 g)
2. Silver exists as two isotopes with atomic masses of 106.9041 and 108.9047 amu. The average atomic mass for silver if the % abundance for each isotope is 51.82 and 48.18 %, respectively is 107.8682 amu.
1. To find the number of dozens of apples in a 5.000 Lbs (2268g) bag, we first need to convert the weight of the bag to grams. 1 Lbs is equal to 453.59237 grams, so the weight of the bag in grams is:
1 dozen of apples = 2112 g
Bag weight = 2268 g
2268 g * (453.59237 g/Lbs) = 10256.99958 Lbs
We are given that 1 dozen of apples is equal to 2112 grams, so we can divide the weight of the bag by the weight of a dozen of apples to find the number of dozens of apples in the bag:
10256.99958 g / 2112 g/dozen = 4.85 dozens
So, there are 4.85 dozens of apples in a 5.000 Lbs (2268g) bag.
2. Average Atomic Mass for Silver:
Atomic mass of isotope 1 (mass 1) = 106.9041 amu
Atomic mass of isotope 2 (mass 2) = 108.9047 amu
% abundance of isotope 1 = 51.82%
% abundance of isotope 2 = 48.18%
The average atomic mass ([tex]A_a_v_g[/tex]) can be calculated using the formula:
[tex]A_a_v_g[/tex] = (mass 1) * (% abundance 1) + (mass 2) * (% abundance 2)
Convert the percentages to decimals (divide by 100):
% abundance 1 = 51.82% = 0.5182
% abundance 2 = 48.18% = 0.4818
Calculate the average atomic mass:
[tex]A_a_v_g[/tex] = (106.9041 amu) * (0.5182) + (108.9047 amu) * (0.4818)
[tex]A_a_v_g[/tex] = 107.8682 amu
The average atomic mass for silver is approximately 107.8682 amu.
