Answer:
It is the most recent idea of the atom and it is proved to be true
Explanation:
Answer:
Average atomic mass = 63.3896
Explanation:
Step 1: Find how much Cu-65 we have
1 - Amount of Cu-63 = Amount of Cu-65
1 - 0.6915 = Amount of Cu-65
Amount of Cu-65 = 0.305
Step 2: Find the average atomic mass of Cu
(0.6915 x 63) + (0.305 x 65) = <em>Average atomic mass</em>
(43.5645) + (19.825) = <em>Average atomic mass</em>
63.3895 = <em>Average atomic mass</em>
Therefore the average atomic mass of Cu is 63.3895 atomic mass units
Answer: $1338.16
Explanation: Total cost of stock= $2568
Total cost of stock including the brokerage
$
Selling price of stock = $3928
Selling price of stock including trading fee=($3928-$7)=$3919
Net Proceeds = Net selling price of stock - Cost Price of stock
Net Proceeds = ($3919 - $2580.84) = $1338.16
