Answer:

#4.20*10^2 J# of energy are required to raise the temperature of this substance by #10°C#.

Explanation:

Here, we're relating a few things: (1) the mass of the substance, (2) its specific heat, and (3) the temperature change, in the following equation:

#q = mC_sDeltaT#

#q = 95.4g* (0.44J)/(g*°C)* 10°C#
#q approx 4.20*10^2 J#
