Answer:
0.46 grams (C₆H₅)₂CO
Explanation:
To find the mass of benzophenone ((C₆H₅)₂CO), you need to (1) convert mmoles to moles and then (2) convert moles to grams (via molar mass). It is important to arrange the conversions/ratios in a way that allows for the cancellation of units. The final answer should have 2 sig figs to match the sig figs of the given value (2.5 mmoles).
Molar Mass ((C₆H₅)₂CO): 13(12.011 g/mol) + 10(1.008 g/mol) + 15.998 g/mol
Molar Mass ((C₆H₅)₂CO): 182.221 g/mol
2.5 mmoles (C₆H₅)₂CO 1 mole 182.221 g
----------------------------------- x ------------------------ x ------------------- =
1,000 mmoles 1 mole
= 0.46 grams (C₆H₅)₂CO

it could be the right answer
The prediction of the products and the balanced form of the above incomplete equation is as follows: Ag + Cu(NO3)2 → Cu + Ag(NO3)2 (option D).
<h3>How to balance a chemical reaction?</h3>
According to this question, silver reacts with copper nitrate to form products that were not stated.
However, this reaction is an example of a displacement reaction, hence, silver will displace or replace copper in the compound to form copper and silver nitrate as products. The reaction is given as follows:
Ag + Cu(NO3)2 → Cu + Ag(NO3)2
This chemical reaction is said to be balanced because the number of moles of each atoms on both sides of the equation is the same.
