The specific heat capacity of an unknown metal is to be found using calorimetry. A 35.0g sample of the metal is placed into a boiling water bath at a temperature of 100.0ºC. In the calorimeter lies 101.1g of water at a temperature of 22.1ºC. After thorough heating of the metal, it is transferred to the calorimeter. The final temperature of the metal/water system is 22.9ºC. Calculate the specific heat capacity of the metal.
The specific heat of an unknown metal is 0.219 J/g.°C. Use Dulong and Petit's equation for finding Molar Mass (Dulong and Petit's constant is 24.6 J/mol.°C) to identify the metal using its Molar Mass from the Periodic table. Ο Ο Ο Ο Ο
if the specific heat of an unknown metal was 0.151 Cal/g•°C, what would be its approximate molar mass?

Calculate the specific heat of a certain unknown metal, if it requires 195 joules of heat to raise the temperature of 12.1 grams of this metal by 34.6 °C.
= What is the specific heat of an unknown metal (mass 2.30 g) if its temperature increased from 15.0 °C to 31.0 °C when absorbing 14.168 J of heat? Round to three significant figures. Provide your answer below: J g°C
Specific Heat Capacity A 21.5-g sample of an unknown metal is heated to 94.0°C and is placed in a insulated container containing 128 g of water at a temperature of 21.4°C. After the metal cools, the final temperature of the metal and water is 25.0°C. Calculate the specific heat capacity of the metal, assuming that no heat escapes to the surroundings. Heat loss=Heat gained. Specific Heat Capacity of water is 4.18 J/g/K in this temperature range. Submit Answer Incompatible units....

what is the specific heat of an unknown metal if when 20.0 grams of the metal were heated from 20.0°C to 100.0°C the metal absorbed 618 J of heat?
Need help with my lab report for specific heat of unknown metal! I need to Find the Specific Heat of Al! I know its Q= M x Cs x Change in Temp I am getting a such a high number am just confused if its right. Here is what I got in Lab: Aluminum Mass of Metal (Mm): 6.128g Mass of water (Mw) : 25 mL Temp of water in calorimeter: 23.6 C Temp of metal in water-bath: 100 C...
