A 1.57-mol sample of oxygen gas is maintained in a 0.650-L container at 296 K. Calculate the pressure of the gas using both the ideal gas law and the van der Waals equation (van der Waals constants for O2 are a = 1.36 L2atm/mol2 and b = 3.18×10-2 L/mol).

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.
