Answer:
Equation 2, because K being more reactive, exchanges position with Pb in PbNO3.
Explanation:
Answer:
1.68L
Explanation:
Step 1:
Data obtained from the question. This includes the following:
Initial Molarity (Mi) = 7M
Initial volume (Vi) 0.6L
Final Molarity (Mf) = 2.5M
Final Volume (Vf) =.?
Step 2:
Determination of the final volume of the solution.
This can be achieved as shown below:
MiVi = MfVf
Divide both side by Mf
Vf = MiVi /Mf
Vf = 7 x 0.6 / 2.5
Vf = 1.68L
Therefore, the new volume of the solution is 1.68L
Use the ideal gas law PV = nRT and manipulate it to solve for n. PV/RT = n.
Convert to SI units:
660ml -> 0.660 L
27 degrees -> 300 K
Leave Pressure as is
Use 62.36368 for R becuase you are using mmHg for Pressure.
Now plug into the equation to get about 0.025928 mols. Divide the 3.30 grams by the mols to get about 127 g/mol.
