Answer: 3.613x10^24
Explanation: Avogadro’s number represents the number of atoms in one mole of substance: 6.022x10^23 atoms/mole. Multiplying the number of moles by this number reveals that, in this sample, 3.613x10^24 atoms of methane are present.
The time taken to the nearest tenth of a minute, would it take the element to decay to 98 grams is 9.897.
<h3>What is half-life?</h3>
Half-life is the time half-time of the total decay of any element.
Given that, Initial amount = 970 grams
Final amount = 98 grams
Half life = 13 minutes
To find the half life
Thus, the time taken to the nearest tenth of a minute, would it take the element to decay to 98 grams is 9.897.

Answer:
Trail Mix
Explanation:
The best description for the snack that Ben is eating would be Trail Mix. This is a very common snack for hikers, hence the name, since it is very healthy and great for taking on hikes since it does not get affected by the sun. This snack was originally called GORP which stands for "good old raisins and peanuts" because the snack originally contained only raisins and peanuts. It has since changed to include various different ingredients such as a variety of nuts, chocolate pieces, dried fruit, cereal etc.
The percent yield is given by the actual and the theoretical yield. The percent yield of the 2.73 gm compound is 80.3%. Thus, option b is correct.
<h3>What is the percent yield?</h3>
The percent yield is the ratio of the actual yield to the theoretical yield. It is calculated as:
% Yield = Actual yield ÷ Theoretical yield × 100%
= 2.73 ÷ 3.84 × 100%
= 71.09 %
As the closest number to 71.09 is 80.3% the percent yield will be 80.3%.
There is no limiting reagent in the reaction between the copper iodide and mercury iodide as the moles of the reactants and the products are in equal quantity.
Hence, option b. there is no limiting reagent in this reaction.
