B2o3(s) + 3c(s) + 3cl2 (g) > 2 bcl3(g) + 3co(g)
what is the mass of carbon required in order to produce 6.00 mol bcl3?
a. 234 g
b. 216 g
c. 108 g
d. 0.375 g

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.
