Answer to Question #170552 in General Chemistry for tori

Question

In a reaction of 10 mL of 0.1 M silver I nitrate, and 10 mL of 0.1 M sodium carbonate, 0.200 grams of silver I carbonate is formed, what is the percent yield?

Answer 1

2 AgNO₃ + Na₂CO₃ $\to$ Ag₂CO₃ + 2NaNO₃

10ml of 0.1M____10ml of 0.1M

1mol_____1mol

0.5 mmol of Ag₂CO₃

When 1mmol AgNO₃ will react 1mmol of Na₂CO₃ (i.e. in excess) so 0.5 mmol of Ag₂CO₃ will formed

0.5/1000 moles of Ag₂CO3

massof Ag₂CO₃ formed =( 0.5/1000)×275.74

= 0.1378

%yield is more than 100%
