Which of the following substance has minimum number of oxygen atoms? A) 1.0 mole of CO2
B) 1.0 mole of O3
C) 1.0 mole of V2O5
D) 1.0 mole of H2O ​

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.

5.6⋅10−^19  j
