Answer:
Barium
Explanation:
The specific heat of a material is a property defined as the amount of energy required to increase the temperature of 1g of this material in 1°C = 1K
In this way, the metal that takes the least amount of energy to increase its temperature is the metal that has the lowest specific heat.
In the problem, this metal is Barium (Ba = 0.201J/gK)
120 grams of NaOH means 3 Moles of NaOH because 40 grams (Molecular Weight in grams) is one mole of NaOH.
Each mole of any substance contain Avogadro’s number of molecules ie., 6.022 x (10 to the power 23).
Hence 3 Moles of NaOH contain 3 times of Avogadro’s number of molecules ie., 3 x 6.022 x (10 to the power 23)
