Calculate the amount of heat (in kJ)necessary to raise the temperature of 53.8 g benzene by 50.6 K.The specific heat capacity of benzene is 1.05 J/g°C.

Question

Quizplus · Accepted Answer

We can use the formula:

q = m × c × ∆T

where q is the heat needed, m is the mass, c is the specific heat, and ∆T is the change in temperature.

Substituting the given values, we get:

q = 53.8 g × 1.05 J/g°C × 50.6 K 
q = 2,862.69 J

Converting J to kJ:

q = 2.86 kJ

Therefore, the answer is D) 2.86 kJ.
