Question

Sodium metal is sometimes used as a cooling agent in heat-exchange units because of its releatively high molar heat capacity fo 28.2 J/(mol·°C). What is the specific heat and molar heat capacity of sodium in J/g·°C?

Accepted Answer

Hello everyone today we are being asked the following question. Tungsten metal has a high strength to weight ratio and is known to withstand high temperatures, making it viable and military and marine industries. The molar heat capacity of tungsten is 24.3 jewels Permal Celsius, calculate the specific heat capacity of tungsten. So first you want to recall our units of specific heat capacity and they are jules programs, centimeters. We then want to recall the molar mass of tungsten. This is gonna be per the periodic table And this is going to be 183.84 g per mole. And lastly, what we're gonna do is we're gonna multiply these two numbers to finally calculate our specific heat capacity. So we will take our 24.3 jewels Permal Celsius and we will multiply that by our molar mass here. That says that for every one mole We have 183.84 g of our tungsten. Our units for Mosul canceled out. However, we will be left with 1.32 jules per gram centimeter as our final answer. And notice how this aligns with our units for specific heat capacity. And with that we have answered the question overall. I hope that this helped. And until next time
