6 mL of 5.00 g/L AgNO3 is added to a coffee-cup calorimeter containing 56.6 mL of 5.00 g/L NaI, with both solutions at 25°C, what mass of AgI forms?
1 answer:
Answer:
Mass of AgI formed=0.352g
Explanation:
AgNO3 + NaI ----‐>AgI + NaNO3
Volume of AgNO3 =5g/L
Mass of AgNO3 =C×V=0.25g
n(AgNO3)= m/Mr=0.0015mol
For NaI
V= 5g/l
Mass= C×v=0.25g
n=m/Mr=0.0017mol
n=0.0015mol
Mass=n× mr=0.352g
