A 62.6-gram piece of heated limestone is placed into 75.0 grams of water at 23.1°C. The limestone and the water come to a final temperature of 51.9°C. The specific heat capacity of water is 4.186 joules/gram degree Celsius, and the specific heat capacity of limestone is 0.921 joules/gram degree Celsius. What was the initial temperature of the limestone? Express your answer to three significant figures.

The initial temperature of the limestone was

208.7°C was the initial temperature of the limestone.

Explanation:

Heat lost by limestone will be equal to heat gained by the water

Mass of limestone =

Specific heat capacity of limestone =

Initial temperature of the limestone =

Final temperature = =T =  51.9°C

Mass of water=

Specific heat capacity of water=

Initial temperature of the water =

Final temperature of water = =T =  51.9°C

On substituting all values:

208.7°C was the initial temperature of the limestone.

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

i think   the answer is c hope i'm right
