Hello dear,

● Answer- 1.21 cal/g/°C

● Explanation-
# Given-
Specific heat of water = 1 cal/g/°C
Density of alcohol = 1×200/250 = 0.8 g/cm^3

# Solution-
Specific heat of alcohol
x = 1 × (60-55) × (130/67) / (0.8 × 10)
x = 1.21 g/cal/°C

Therefore specific heat of alcohol is 1.21 g/cal/°C.

Hope this is useful...
