Given that the heat of fusion of ice is 334 J/g, what is the total amount of heat required to completely melt 347 grams of ice at its melting point?
A
334 J
B
347 J
C
1,036 J
D
115,798 J
Verified step by step guidance1
Identify the given information: the heat of fusion of ice is 334 J/g, and the mass of ice is 347 g.
Recall the formula to calculate the heat required for a phase change: \(Q = m \times \Delta H_{fus}\), where \(Q\) is the heat absorbed or released, \(m\) is the mass, and \(\Delta H_{fus}\) is the heat of fusion.
Substitute the known values into the formula: \(Q = 347\,\text{g} \times 334\,\text{J/g}\).
Multiply the mass by the heat of fusion to find the total heat required to melt the ice completely.
Express the final answer in joules (J), which represents the total heat needed to convert 347 grams of ice at its melting point into liquid water.
