a gas occupies a volume of 224 cm and a pressure of 1.51 bars. if the gas expands to a volume of 578 cm,
what will the new pressure be? (assume the temperature remains constant.)

The new pressure is 0.5852 bar

Explanation:

Since the temperature is constant, we can apply Boyle's Law.

Boyle's Law states that at constant temperature, pV = constant

Therefore, the new pressure is 0.5852 bar

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.
