What does q = 0.75 g x 0.897 J/g•°C x 22°C equal?

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.
