Calculate the vapor pressure in a sealed flask containing 55.0 g of ethylene glycol, C2H6O2, dissolved in 155 g of water at 25.0°C. The vapor pressure of pure water at 25.0°C is 23.8 torr.

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.

the answers would be

the first one and the second one
