14. Using the equation of q = nCΔT determine the amount of energy required to raise the temperature of 24g of water 80ᵒC, with a heat capacity of 75.3 J/(mol*ᵒC )
I don't understand. You have the formula and all of the numbers. What's your problem?
To find the amount of energy required to raise the temperature of 24g of water by 80ᵒC, we can use the equation q = n*C*ΔT.
First, we need to convert the mass of water from grams to moles. To do this, we'll use the molar mass of water, which is approximately 18 g/mol. Divide the mass by the molar mass:
n = 24g / 18 g/mol = 1.333 mol (rounded to 3 decimal places)
Next, we can substitute the values into the equation:
q = 1.333 mol * 75.3 J/(mol*ᵒC) * 80ᵒC
Now, we can calculate the amount of energy required:
q = 1.333 mol * 75.3 J/(mol*ᵒC) * 80ᵒC = 8,048 J
Therefore, the amount of energy required to raise the temperature of 24g of water by 80ᵒC, with a heat capacity of 75.3 J/(mol*ᵒC), is 8,048 J.
