A 96.4g piece of an unknown metal was heated to 91.7°C and then placed into a beaker containing 100g of water at 24.5°C. The temperature stops changing at 26.2°C. What is the specific heat of the metal?

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.

that's what i got you can count the number of atoms

catya your not at all which answer i've seen you do this on another question!
