<u>Answer:</u> The average atomic mass of copper is 63.546 amu
<u>Explanation:</u>
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
.....(1)
- <u>For isotope 1 (Cu-63):</u>
Mass of isotope 1 = 62.93 amu
Percentage abundance of isotope 1 = 69.2 %
Fractional abundance of isotope 1 = 0.692
- <u>For isotope 2 (Cu-65):</u>
Mass of isotope 2 = 64.93 amu
Percentage abundance of isotope 2 = 30.8 %
Fractional abundance of isotope 2 = 0.308
Putting values in equation 1, we get:
Hence, the average atomic mass of copper is 63.546 amu
First, make sure all three measurements have the same unit (I recommend meters because that's what the question calls for)
1.0m=1.0m
5.6cm=0.056m
2.1mm=0.0021m
Then, you just want to multiply the three together to get the total volume.
1.0X0.056X0.0021=0.0001176 or 0.00012, if your teacher wants you to use proper sig figs
70 bags is the answer.
They add “They put 7 pieces of candy in each bag to throw you off”
To find the answer just divide 28 bags by 4 days to get how many bags they make in 1 day. Take that number “7” and multiply it by 10 days. The answer is then 70.
