<h3>Answer:</h3>
63.5456 amu
<h3>Solution:</h3>
Data Given:
Atomic Mass of ⁶³Cu = 62.9296 amu
Natural Abundance of ⁶³Cu = 69.17 %
Atomic Mass of ⁶⁵Cu = 64.9278 amu
Natural Abundance of ⁶⁵Cu = 30.83 %
Formula Used:
Average Atomic Mass = [(Atomic Mass of ⁶³Cu × Natural Abundance of ⁶³Cu) + (Atomic Mass of ⁶⁵Cu × Natural Abundance of ⁶⁵Cu)] ÷ 100
Putting values,
Average Atomic Mass = [(62.9296 × 69.17) + (64.9278 × 30.83)] ÷ 100
Average Atomic Mass = [(4352.8404) + (2001.7241)] ÷ 100
Average Atomic Mass = 6354.5645 ÷ 100
Average Atomic Mass = 63.5456 amu
I believe that there are 12 oxygen atoms in aluminum sulfate, And 1 Sulfur and 2 aluminum. If you need anything else let me know.
Answer:
Eght: 0
Explanation:
The work formula is W = F*d where d is displacement (which means the direction matters)
Same amount of work.
Eight
Time does not matter in Work. Force and Distance do.
F = 50 N
s = 0 The only work you have done is move the ball above your head. Thereafter you just held it.
t = 15 but no work is done. Tell your tired muscles that as they try and deal with holding a 5 kg mass above you head.
W = 0
Nine
Again from the last question you should be able to tell that time does not matter. The force is the same for both of you (that's why he's your identical twin).
So the work is the same. You both weigh the same. You both went the same distance.

3:6:2 is the correct answer
