The average mass of a carbon atom is 12.011. assuming you were able to pick up only one carbon atom, the chance that you would randomly get one with a mass of 12.011 is a. 0%. b. 0.011%. c. about 12%. d. 12.011%. e. greater than 50%. f. none of these is true. explain.

Option (a) is the correct answer.

Explanation:

Average atomic mass of an element is defined as the sum of masses of its isotopes and each of them is multiplied by its natural abundance.

For example, in there is 99% and 1% is present. Hence, its mass will be calculated as follows.

          =

          = 11.88 + 0.13

          = 12.01

This means one atom of carbon will not contribute to its mass as 12.011 but isotopes of carbon will attribute to it.

Thus, we can conclude that assuming you were able to pick up only one carbon atom, the chance that you would randomly get one with a mass of 12.011 is 0%.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
