Answer:

The specific heat capacity of the substance is #"0.33 cal·g"^"-1""°C"^"-1"#.

Explanation:

The amount of heat required is determined from the formula

#q = mcΔT#,

where

  • #q# is the amount of heat transferred
  • #m# is the mass of the substance
  • #c# is the specific heat capacity of the substance
  • #ΔT# is the change in temperature

#q = "1560 cal"#
#m = "312 g"#
#ΔT = "15 °C"#

#c = q/(mΔT) = "1560 cal"/("312 g × 15 °C") = "0.33 cal·g"^"-1""°C"^"-1"#
