Answer:
m AgBr = 1.193 g
Explanation:
- AgNO3 + HBr → AgBr + HNO3
∴ V AgNO3 = 41.8 mL = 0.0418 L
∴ [ AgNO3 ] = 0.152 mol/L
∴ Mw AgBr = 187.77 g/mol
⇒ n AgNO3 = (0.0418 L)(0.152 mol/L) = 6.3536 E-3 mol AgNO3
⇒ n AgBr = (6.3536 E-3 mol AgNO3)(mol AgBr/mol AgNO3) = 6.3536 E-3 mol AgBr
⇒ m AgBr = (6.3536 E-3 mol AgBr)(187.77 g/mol) = 1.193 g AgBr
