The amount of heat required to raise the temperature of a substance can be calculated using the following formula:
Q = m * c * ΔT
Where:
Q = heat (in Joules)
m = mass of the substance (in grams)
c = specific heat of the substance (in J/(g°C))
ΔT = change in temperature (in °C)
Substituting the given values into the formula, we get:
Q = 20.0 g * 0.444 J/(g°C) * (72.30 °C - 26.0 °C)
Q = 20.0 g * 0.444 J/(g°C) * 46.30 °C
Q = 20.0 g * 20.5032 J/g
Q = 410.06 J
