Answer:
2,950
joules.
Explanation:
The units don’t need conversion, and the formula doesn’t need changing.
First, determine the energy required to melt the ice:
Q = mHf
Q = 6.70 g × 334
Q = 2,240 J
Next, determine the energy needed to raise the temperature of the newly melted water:
Q = mCΔT
Q = 6.70 g × 4.186 × (25.4°C – 0.0°C)
Q = 712 J
Now, add the energy values. Express the answer to 3 significant figures:
2,240 J + 712 J = 2,950 J.
