#"13.9 g"#

Explanation:

Use this equation

#"Q = mSΔT"#

Where

  • #"Q ="# Heat added/released
  • #"m ="# Mass of sample
  • #"S ="# Specific heat of sample
  • #"ΔT ="# Change in Temperature

#"m" = "Q"/"SΔT"#

#color(white)("m") = "2153 J"/"4.184 J/g°C × (81 – 44)°C"#

#color(white)("m") = 13.9\ "g"#
