The average atomic mass of Sn is 118.71 g/mol
the percentage of heaviest Sn is 5.80%
the given mass of Sn is 82g
The total moles of Sn will be = mass / atomic mass = 82/118.71=0.691
Total atoms of Sn in 82g = 
the percentage of heaviest Sn is 5.80%
So the total atoms of 
= 5.80% X 
Total atoms of =
atoms
the mass of will be = 
<u>The given reaction is:</u>
F2 + ClO2 → 2FClO2
Rate = k[F2][ClO2]
<u>Explanation:</u>
The possible mechanism for this reaction can be broken down into two steps with the slow step being the rate determining step
Step 1: F2 + ClO2 → FClO2 + F ----------- Slow
Step 2: F + ClO2 → FClO2 ----------- Fast
-----------------------------------------------------------
Overall: F2 + 2ClO2 → 2FClO2
Rate = k[F2][ClO2]
Answer:
For dispensing, weigh it out.
Yes, a different solvent such as ethanol could be used.
Explanation:
Besides using various methods for melting the <em>tert</em>-butanol in order to pour it out and measure a given volume, the <em>tert</em>-butanol could be weighed out in a beaker using a scale. Depending on the temperature of the laboratory, the <em>tert</em>-butanol could be a solid or a liquid/solid mixture.
In general, a different solvent such as ethanol could be used in place of <em>tert</em>-butanol as long as the solvent is a low molecular weight alcohol.
