100.0 mL of 2.000 M sodium hydroxide is mixed with 200.0 mL of 1.000 M nitric acid. Both solutions are initially at a temperature of 23.00 °C, the resulting sodium nitrate solution has a temperature of 31.91 °C What is the heat of neutralization (H) for this reaction? [Assume that the density and heat capacity of all solutions are identical to that of water: 1.000 g/mL and 1.000 cal/g°C and that there is no loss of heat from the solution.]

What reaction? first write the reaction

  • aaronq
Then use: \(q=m*C_p*\Delta T\) and \(\Delta H^o=\dfrac{q}{n}\) q= heat, m=mass, \(\Delta T\)= change in temp, n= moles

@aaronq i have the reaction written out but how do i find the mass... which mass do i use for that equation?

use the mass of the product

use the mass of the salt in the product convert to moles and divide by the stoichiometric coefficient (i'm pretty sure, since you have to normalize for the reaction)
