Answer:
The molarity is: 1 M
Explanation:
We define molarity as an amount of moles in 1000ml of solution (1 liter)
500ml---------0,5 moles AlCl3
1000ml------x= (1000ml x 0,5 moles AlCl3)/500ml = 1 moles ACl3--> 1 M

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
