The heat capacity of a bomb calorimeter was determined by burning 6.79 g of methane (energy of combustion = -802 kj/mol ch4) in the bomb. the temperature changed by 15.7°c. (a) what is the heat capacity of the bomb?

The answer to your question is: Cp = 7.52 kJ/g°C

Explanation:

Data

Cp = ?

mass = 6.79 g

Energy = -802 kJ/mol   CH₄

ΔT = 15.7°C

Formula

Q = mCpΔT

Solve for Cp

Process

- Convert energy to J

                                     -802kJ/mol = - 802 000 J/mol

- Calculate heat capacity

                                 Cp = 7523 J/ g°C   or

                                 Cp = 7.52 kJ/g°C

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
