If 0.076 mol of hydrochloric acid (HCTD is mixed with 0.076 mol of sodium hydrox

Question

If 0.076 mol of hydrochloric acid (HCTD is mixed with 0.076 mol of sodium hydroxide (NaOH) in a "coffee cup" calorimeter, the temperature of 5.8 g of the resulting solution increases from 25.0°C to 29.5°C. Given that the energy released is 1.2 x 101 cal when the specific heat of the resulting solution is 1.00 cal/g-oC, use a conversion factor to convert the energy released to joules (J). Enter your answer in scientific notation. Be sure to answer all parts. References eBook & Resources Multipart Answer pe here to search

Explanation / Answer

Relation between cal and J is,

1 cal = 4.184 J

Then,

1.2 * 101 cal = 4.184 * 1.2 * 101 J

= 5.02 * 101 J
