Answer:
1. 11g
2. 909
Explanation:
To get the Weight of a 109 washers who weigh 0.110g each we have to find the ratio of Weight of one washer to 1 washer and multiply by 100
= 100 washers x 0.110g/1 washer
= 11g
Therefore the mass of 100 washers is 11 grams
2.
Then the number of washers =
100g x 1washer/0.110g
= 909
Therefore number of washers = 909
Explanation: Outer shell electronic configuration for Group 18 is :
( have 8 electrons in the outer shell)
The electronic configurations for other groups are:
( have 1 electron in the outer shell}
( have 2 electrons in the outer shell)
( have 5 electrons in the outer shell)
( have 6 electrons in the outer shell)
( have 7 electrons in the outer shell)
Comparing the electron configurations of group 18 to other groups.
Group 18 has fully filled outer shell, that is 8 electrons in the outer shell, while others are partially filled.
