Answer:
10.22g
Explanation:
Using the formula as follows:
Q = m × c × ∆T
Where;
Q = amount of heat required (J)
m = mass of substance (g)
c = specific heat of substance (J/g°C)
∆T = change in temperature (°C)
According to the information given in this question;
Q = 341J
m = ?
∆T = 55.0ºC - 18.0ºC = 37°C
c of aluminum = 0.902J/g°C
Using Q = m × c × ∆T
341 = m × 0.902 × 37
341 = 33.374m
m = 341 ÷ 33.374
m = 10.22g
