A volume of 100. mL of H2O is initially at room temperature (22.00 °C). A chilled steel rod at 2.00 °C is placed in the water. If the final temperature of the system is 21.00 °C, what is the mass of the steel bar?

Use the following values:

specific heat of water = 4.18 J/(g. °C)
specific heat of steel = 0.452 J/(g.)

Express your answer to three significant figures and include the appropriate units.

it is the most commonly accepted one

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

12 is it do you think so
