1.0g of sodium hydroxide, NaOH, was added to 99.0g of water. The temperature of the solution increased from 18.0^C to 20.5^C. The specific heat capacity of the solution is 4.18 J g ^-1 K^-1. Which expressed gives the heat EVOLVED in kJmol^-1.
A. (2.5 ×100 ×4.18 ×1000)/40
B. (2.5 ×100 ×4.18 )/(40 ×1000)
C. (2.5 ×100 ×4.18 ×40 )/1000
D.(2.5 ×1 ×4.18 ×40 )/1000
Is the question asking me to find the specific heat capacity, in which case I would use E = mc * change in temperature.
which would be = 100 x 4.18 x 2.5
What does it mean by heat EVOLVED?
Thanks for the help : )
Okay so if I have to use e = mc x change in temp. Which answer is correct A, B, C, D?
A. (2.5 ×100 ×4.18 ×1000)/40
B. (2.5 ×100 ×4.18 )/(40 ×1000)
C. (2.5 ×100 ×4.18 ×40 )/1000
D.(2.5 ×1 ×4.18 ×40 )/1000
