Answer: of liquid sodium is required.
Explanation: To calculate the mass of liquid sodium, we use the formula:
where,
q = heat required, (Conversion factor: 1MJ = 1000000J)
m = Mass of liquid sodium,
M = Molar mass of liquid sodium,
c = Specific heat capacity,
= change in temperature,
(Conversion factor: 0°C = 273K)
Putting values in above equation, we get:
