Question

2 AgC2H3O2 (aq) + Na2CO3 (s) --> 2 NaC2H3O2 (aq) + Ag2CO3 (s)

If 15.0 grams of silver carbonate is produced in this reaction, how many grams of sodium carbonate were used?

Answer 1

$\nu(Ag_2CO_3)=\nu(Na_2CO_3)$

$\nu(Ag_2CO_3)=mass(Ag_2CO_3)//Molar(Ag_2CO_3)=15,0/275,75=0,0544 moles$

$\nu(Na_2CO_3)=0,0544 moles$
