Calculate the final temperature of the system: a 50.0 gram sample of water initially at 100 °c and a 100 gram sample initially at 27.32 °c are mixed. the specific heat of water is 4.184 j/gc). record your answer in scientific notation using 3 significant figures.

The final temperature of the water system is 51.5 °C.

Explanation:

A 50.0 gram sample of water initially at 100 °C

Mass of the water = 50 g

Initial temperature of the water =

Final temperature of the water after mixing =

-Q' = heat lost by 50.0 g of water

A 100.0 gram sample of water initially at 27.32°C

Mass of the water ,m'= 10.00 g

Initial temperature of the water =

Final temperature of the water after mixing =

Q = heat gained by 100.0 g of water after mixing

-Q'=Q (Energy remains conserved)

The final temperature of the water system is 51.5 °C.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
