23 grams of sodium reacts with 244 cm3 of water that is initially at 293 k. it produces an enthalpy change of 71 kj. what is the final temperature of the water? the specific heat capacity of water is 4.18 j/k g.

Given mass of Na is 23 g

Volume of water =

Mass of water =

Total solution mass = 23 g + 244 g = 267 g

Specific heat capacity of water = 4.18 J/K.g

Equation relating mass, heat, specific heat capacity and temperature change is:

ΔT

Tfinal = 356.6 K

Therefore, the final temperature of water will be 356.6 K
