by 68.0°C. What is the mass of the coin?
Please helppp!!!
The mass of the copper coin placed in 101g of water is 135.3g.
The mass of the copper coin can be calculated using the following expression:
Since; Q = mc∆T
Where;
According to the question;
COPPER METAL:
WATER:
m = 101g
c = 4.18 J/g°C
∆T = 8.39°C
⇒ 101 × 4.18 × 8.39 = (0.385 × m × 68)
⇒ 3542.09 = 26.18m
⇒ m = 3542.09 ÷ 26.18
⇒ m = 135.3g
Therefore, the mass of the copper coin placed in 101g of water is 135.3g.
