    Answer:

    14.8005 Joules

    Explanation:

    This question is describing the calculation for the amount of heat (Q) a substance absorbs or releases. The amount of heat, Q, is calculated using the formula:

    Q = m × c × ∆T

    Where;

    Q = amount of heat (Joules)

    m = mass of substance (g)

    c = specific heat of substance (J/g°C)

    ∆T = change in temperature of substance i.e. final temperature – initial temperature (°C).

    According to this question, the following expression is given:

    q = 0.75 g x 0.897 J/g•°C x 22°C

    To calculate this further, this will equal to: 14.8005

    This means that the amount of heat, q, absorbed or released by that substance is equal to 14.8005 Joules.
