Answer: 401.664J
Step-by-step explanation:
Formula for energy required = mass x specific heat capacity x change in temperature
First of all, check the units and make sure they correspond
Grams to grams and °C to °C
So we can go ahead and multiply
If we were given a parameter in kilogram or kelvin, might've had to convert
Energy required = 19.2 x 4.184 x 5 = 401.664 J
You could approximate to 401.7J
