It takes 49.0j to raise the temperature of an 11.5g piece of unknown metal from 13.0? c to 24.3? c. what is the specific heat for the metal? express your answer numerically, in j/g? ? molar heat capacity of silver is 25.35 j/mol? ? c. how much energy would it take to raise the temperature of 11.5g of silver by 10.1? c? express your answer numerically, in is the specific heat of silver?

c = 0.377 J/g.°C

c = 0.2350 J/g.°C

J = 27.3 J

Explanation:

We can calculate the heat (Q) absorbed or released by a substance using the following expression.

Q = c × m × ΔT

where,

c: specific heat

m: mass

ΔT: change in the temperature

It takes 49.0J to raise the temperature of an 11.5g piece of unknown metal from 13.0°C to 24.3°C. What is the specific heat for the metal? Express your answer numerically, in J/g.°C

Q = c × m × ΔT

49.0 J = c × 11.5 g × (24.3°C - 13.0°C)

c = 0.377 J/g.°C

The molar heat capacity of silver is 25.35 J/mol.°C. How much energy would it take to raise the temperature of 11.5g of silver by 10.1°C? Express your answer numerically, in Joules. What is the specific heat of silver?

The molar mass of silver is 107.87 g/mol. The specific heat of silver is:

Q = c × m × ΔT

Q = (0.2350 J/g.°C) × 11.5 g × 10.1°C = 27.3 J

the answer is 0.42 is that is an option. this question provides no info
