At what temperature will a sample of oxygen gas with a volume of 0.110 L at 12°C and 822 mmHg occupy a volume of 345 mL at a pressure of 578 mm Hg? Assume the amount of the oxygen gas does not change.

your answer would be a. 12.5 kg

answer: c.

explanation:

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.
