A 260.0 −mL buffer solution initially contains 2.5×10−2 M of HCHO2 and 2.5×10−2 M of NaCHO2
FinnZ [79.3K]

The mass of HCHO2 and NaCHO2 to be added to the buffer solution are 0.23g and 0.44g respectively

Data;

  • Volume of solution = 260mL
  • conc. of HCHO2 = 2.5*10^-2M
  • conc. of NaCHO2 = 2.5*10^-2M

<h3>Mass of Reagent Added</h3>

To calculate the mass of reagent added,  let's start with HCHO2

The mass of HCHO2 to be added is the number of moles of HCHO2 multiplied by it's molar mass.

260*10^-^3 * 2.5*10^-^2 * 46 = 0.229 = 0.23g

The mass of NaCHO2 to be added in the buffer solution is

260*10^-^3*2.5*10^-^2*68 = 0.442 = 0.44g

The mass of HCHO2 and NaCHO2 to be added to the buffer solution are 0.23g and 0.44g respectively

Help!!!
Vedmedyk [2.9K]

Answer:

3.213J/mol

Explanation:

first specific heat capacity of water = 4200J/Kg K

Q=mass×temperature difference×specific heat capacity

Q=1.53×(24.3-20)×4200

Q=25.704 J

heat of solution= quantity of heat ÷ amount of substance

heat of solution= 25.704÷8

heat of solution= 3.213J/mol
