When 50 G of a Certain Material At $100 ^ { \circ } \mathrm { C }$

When 50 g of a certain material at $100 ^ { \circ } \mathrm { C }$ is mixed with 100 g of water at $0 ^ { \circ } \mathrm { C }$ the final temperature is $40 ^ { \circ } \mathrm { C }$ What is the specific heat of the material? The specific heat of water is $1.00 \mathrm { kcal } / \mathrm { kq } \cdot \mathrm { C } ^ { \circ }$

A) $0.33 \mathrm { kcal } / \mathrm { kg } \cdot \mathrm { C } ^ { \circ }$
B) $7.5 \mathrm { kcal } / \mathrm { kg } \cdot \mathrm { C } ^ { \circ }$
C) $1.3 \mathrm { kcal } / \mathrm { kg } \cdot \mathrm { C } ^ { \circ }$
D) $0.75 \mathrm { kcal } / \mathrm { kg } \cdot \mathrm { C } ^ { \circ }$
