Answer:
0.385J/g°C
Explanation:
Using the following formula;
Q = m. c. ∆T
Where;
Q = amount of heat (joules)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
According to the provided information in this question;
Q = 318 cal
1 calorie = 4.184J
318 cal = 318 × 4.184 = 1330.512J
m = 279g
∆T = 27.2°C - 14.8°C = 12.4°C
Hence, using Q = m. c. ∆T
c = Q ÷ (m. ∆T)
c = 1330.512 ÷ (279 × 12.4)
c = 1330.512 ÷ 3459.6
c = 0.385
Therefore, the specific heat of copper is 0.385J/g°C
Answer:
Hey there!
Gold would have a greater mass, because density is mass/volume, and if the density is greater, so is the mass.
Let me know if this helps :)
Answer:
The answer to your question is: 1.61 l
Explanation:
Data
Volume = ?
Molarity = 4.5 M
# of moles = 7.25 mol
Molarity = # of moles / volume
Volume = # of moles / molarity
Process
Volume = 7.25 moles / 4.5
Volume = 1.61 liters
