Observe the balloons A and B above. Both balloons have a temperature of 25.0°C,
contain 0.50 moles of gas sealed by the knot at the bottom, and have a volume of
2.2 L.
CLE
If balloon A is placed in a freezer with a temperature of -5.50°C, which of the
following statements regarding the volumes of the balloons is accurate?

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.
