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
In order to know the number of moles from the given mass, the conversion factor to be used is the average atomic mass of Calcium which is equal to 40.08 g/mol. But first, let's convert mass from grams to kilograms knowing that there are 1,000 g in every 1 kg.
Mass = 351 kg * 1,000g/1 kg = 351,000 grams
Number of moles = 351,000 g * 1 mol/40.08 g = 8,757.5 moles Calcium
The atoms have more energy levels
