Answer:
Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation
Molar mass of Li = 6.9 g/mol
6.9 g -------------------- 6.0x10²³ atoms
g -------------------- 2.75x10^21 atoms
6.0x10²³ g = 6.9 * (2.75x10^21)
6.0x10²³ g = 1.8975x10²²
g = 1.8975x10²² / 6.0x10²³
x = 0,0317 g
