Answer:
5g sucrose
Explanation:
The solution of 50mL can be assumed to the same density as water (1g/mL), and therefore a mass of 50g. A solution of 10% sucrose has 5g of sucrose:
(50g)(0.10) = 5g
In order to make the solution, 5g of sucrose should be added to about 40mL of water and dissolved completely. The solution may then be poured into a 50mL volumetric flask and diluted to the mark.
4Ag + 2H2S + O2 -> 2Ag2S + 2H20 i’m pretty sure that’s correct
