Question

P

Answer 1

Answer:

m = 1538.5 g

Explanation:

To answer this question, use the equation for specific heat:

$q=mc \Delta T$

Where q is the total heat energy, m is the mass, c is the specific heat of the substance (in this case water), and delta T is the temperature change.

You will be expected to know the specific heat of water, which is 4.186 J/g/C. Using the information in the question:

$41840=m(4.186)(28.5-22)\\41840=27.2m\\m=1538.2$

The final answer, 1538.5 g, is closest.
