In a calorimetry experiment 60 ml of 0.400m of cuso4 solution is mixed with 40 ml of 0.700m naoh. the initial temperature of both solutions is 21.4 c and the final temperature 25.6 c. calculate the enthalpy change of this reaction in kj/mol.

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.
