  Homework Statement
  The melting point of a solid is 90 C. What is the heat required to change 2.5 kg of this solid at 30 C to a liquid
  
  The specific heat of the solid is (390 j/KG.C) and its heat fusion is (4000 J/KG)
  Relevant Equations
  Q=mC ΔT heat capacity
  Q=mHf heat of fusion
  Q1=2.5(390)(90-30) =58500
  
  Q2=2.5(4000) = 10000
  
  Qtotal = 58500+10000
  
  Q=68500
  
  =6.8x10^4
  
  my teacher sent this as a homework but the options were
  4.9x10^4 J
  1x10^4 J
  6.8x10^5 J
  5.9x10^4 J
  
  im confused is is this a typo or did i do something wrong
