<u>Answer:</u> The amount of heat absorbed by the solution is 2.795 kJ
<u>Explanation:</u>
To calculate the mass of water, we use the equation:
Density of water = 1 g/mL
Volume of water = [70 + 70] = 140 mL
Putting values in above equation, we get:
To calculate the heat absorbed, we use the equation:
where,
q = heat absorbed
m = mass of water = 140 g
c = heat capacity of water = 4.186 J/g°C
= change in temperature =
Putting values in above equation, we get:
Hence, the amount of heat absorbed by the solution is 2.795 kJ
