An unknown mass of each of the following substances, initially at 23.0, absorbs 1910 of heat. The final temperature is recorded as indicated. Find the mass of the substance, given: Pyrex glass (55.5)

The data not given here is the specific heat capacity of pyrex glass equal to 0.75 (J/g °C). In this case, heat is equal to mass x specific heat capacity x temperature rise. Temperature difference is then equal to 1910 J / 0.75 J/g °C / 23 g equal to 110. 75 °C
