Answer: 82.3 g
Step-by-step explanation:Moles Cu = 300 g x 1 mol Cu/63.55 g = 4.72 moles Cu
Moles Zn = 4/15(4.72) = 1.26 moles
mass Zn = 1.26 moles x 65.38 g/mol =

Answer: 4.75%.
Step-by-step explanation:
Given: The mean weight
of 500 college students is 70 kg and the standard deviation
is 3 kg.
Let X be the number of students weight over 75 kg.
If the weight is normally distributed, then the probability that students weigh over 75 kg:

Hence, the percentage of students weigh over 75 kg = 4.75%.
Answer:
Step-by-step explanation:
