Approximately how many moles of chlorine makeup 1.79 x 10^23 atoms of chlorine

Given the atoms of Chlorine, Cl =

1 mol of any substance has Avagadro number of formual units (atoms, molecules, ions)

are present per each mole chlorine.

The conversion factor used to convert atoms to moles of chlorine is,

Calculating the moles of Cl that make up :

*=0.279 mol Chlorine

Therefore, 0.297 mol Cl make up

the formula would be mgso4

mgso[subscript]4

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.
