Calculate the volume of chlorine molecules produced at room temperature and pressure, when 234 g of sodium chloride are electrolysed. (1 mole of chlorine molecules has a volume of 24 dm3 at room temperature and pressure). Show your working

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.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
