How much heat energy is required to raise the temperature of 0.367 kg of copper from 23.0 C to 60.0 C ? The specific heat of cop
mojhsa [17]
Note: We must keep the units we use consistent. The Cp is given in cal/gC so we will use cal for energy, grams for mass and C for temperature.
1)
Heat supplied can be calculated using:
Q = mCpΔT; where m is the mass, Cp is the specific heat capacity and ΔT is the temperature change.
Q = 367 x 0.092 x (60 - 23)
Q = 125 Cal

2)
Using the same equation:
125 = 60 x 0.092 x (T - 23)
T = 45.6 C

What is the molarity of a HCl solution that contains 8.53 g of HCl in 372 mL of solution?
kirill [66]
First you find moles of HCl.

8.53gHCl(1 mol HCl/36.46gHCl)=0.234mol HCl

Then since molar it is mol/L you divide the number on moles of HCl by the amount of solution in L (0.372L).
Good luck!
