Hello,
By considering the rate law:
![ln(\frac{[CO_2]}{[CO_2]_0} )=-kt\\](https://tex.z-dn.net/?f=ln%28%5Cfrac%7B%5BCO_2%5D%7D%7B%5BCO_2%5D_0%7D%20%29%3D-kt%5C%5C)
Solving for the time, we've got:
![k=-\frac{ln (\frac{[CO_2]}{[CO_2]_0 })}{t}\\\\k=-\frac{ln(\frac{56.0mmol*dm^{-3} }{220mmol*dm^{-3} })}{1.22x10^{4}s }\\ \\k=1.12x10^{-4}s](https://tex.z-dn.net/?f=k%3D-%5Cfrac%7Bln%20%28%5Cfrac%7B%5BCO_2%5D%7D%7B%5BCO_2%5D_0%20%7D%29%7D%7Bt%7D%5C%5C%5C%5Ck%3D-%5Cfrac%7Bln%28%5Cfrac%7B56.0mmol%2Adm%5E%7B-3%7D%20%7D%7B220mmol%2Adm%5E%7B-3%7D%20%7D%29%7D%7B1.22x10%5E%7B4%7Ds%20%7D%5C%5C%20%20%5C%5Ck%3D1.12x10%5E%7B-4%7Ds)

Rule for multiplying Significant Figures:
- The product is limited to the number of sig figs equal to the least number of sig figs in the problem
Explanation:
52.733 has 5 significant figures and 48.21 has 4 significant figures. Therefore, the answer given must have 4 significant figures.
52.733(48.21) = 2542.25793
This answer round to have 4 significant figures is 2542.
For the answer to the question above asking what mass will the balance report for the cylinder of iron if a <span>cylinder of iron has a mass of 23.45 g. If it is placed on an electronic balance that reports all masses 18.00% too low due to miscalibration,
</span>A cube has a volume of 8.0 cm3 and a mass of 21.6 grams
Using an electronic analytical balance of graduated cylinder.
The density of iron is 7.87 g/mL.
