Lithium metal is a highly reactive metal that oxidizes instantly in water or air. Given the data below, calculate the energy required to heat 10.0 g of Li from 150.0 C to 200.0 C.

Molar heat capacity (solid) = 3.58 J/C mol
Molar heat capacity (liquid) = 4.379 J/C mol
Melting point = 180.5 C
Boiling point = 1342 C
Heat of fusion = 3.00 kJ/mol
Heat of vaporization = 147.1 kJ/mol
