    87.3 calories of heat is required.

    Explanation:

    Heat = mcΔT

    m = mass, c = specific heat of silver, T = temperature

    H = 57.8 g * 0.057 cal/g°C * (43.5 - 17 °C)

    H = 57.8 * 0.057 * 26.5

    H = 87.3069 cal.

    The heat required to raise the temperature of 57.8 g of silver from 17 °C to 43.5 °C is 87.3 calories.
