411.984 grams
The atomic mass of Silver is 107.8682 by the periodic chart I have here. That means that 1 mole of Silver masses
107.8682 grams if the Silver is pure.
I mole of any element like silver is also 6.022 X 10^23 atoms of silver.
10^24 atoms is therefore more than a mole. You specified
2.3 x 10^24 atoms, so the number of moles will be
(2.3 X 10^24)divided by 6.022 X 10^23 = 3.819 moles
this number X 107.8682 grams/mole gives us 411.984 grams
there is not context random people cant solve this because there is no way to know what the chart means and also don't fake 40 points. I'm sorry but if you can add context I might be able to help :/

hope this helped :))
correct me if i’m wrong
Answer:
CH₅N
Explanation:
In the combustion, all of the C in the compound was used to produce CO₂ in a 1:1 ratio. Thus, the moles of CO₂ (MW 44.01 g/mol) produced equals the moles of C in the compound:
(44.0 g)(mol/44.01g) = 0.99977 mol CO₂ = 0.99977... mol C
Similarly, all of the H in the compound was used to produce H₂O in a ratio of 2H:1H₂O. The moles of H₂O (MW 18.02 g/mol) produced was:
(45.0 g)(mol/18.02g) = 2.497...mol H₂O
Moles of H is found using the molar ratio of 2H:1H₂O:
(2.497...mol H₂O)(2H/1H₂O) = 4.994...mol H
The ratio of H to C in the compound is:
(4.994...mol H)/(0.99977... mol C) = 5 H:C
Some NO₂ was produced from the N in the compound. Assuming a 1:1 ratio of C:N, the simplest empirical formula is: CH₅N.
