Question

A sample of an unknown substance has a mass of 89.5 g. If 345.2 J of heat are required to heat the substance from 285 K to 305 K, what is the specific heat of the substance?

Answer: ____ J/g•K

Answer 1

0.193 J/g*K on edg

Step-by-step explanation:

I just took it

Answer 2

Heat gained in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:

Heat = mC(T2-T1)
345.2 = 89.5(C)(305 - 285)
C = 0.1928 J/g•K
