Question

agno₃ + hcl → agcl + hno₃
50.0 ml of 0.20 m agno₃ is added to
50.0 ml of 0.20 m hcl. the resulting
temperature change is an increase of
1.60 °c.
$c_{sol} = 4.20$ j/g °c $d_{sol} = 1.02$ g/ml $c_{cal} = 5.60$ j/°c
what is the mass of the solution?
$\text{mass}_{sol} = ?$ g

Explanation:

Step1: Calculate total volume of solution

The volume of \(AgNO_3\) is \(50.0\) mL and the volume of \(HCl\) is \(50.0\) mL. So total volume \(V = 50.0 + 50.0 = 100.0\) mL.

Step2: Use density to find mass

Density \(d_{sol}=1.02\) g/mL, and mass \(m = d\times V\). So \(m = 1.02\) g/mL \(\times 100.0\) mL.

Answer:

\(102\)
