Understand the Beer-Lambert law for absorbance, A = ɛ x l x c. The standard equation for absorbance is A = ɛ x l x c, where A is the amount of light absorbed by the sample for a given wavelength, ɛ is the molar absorptivity, l is the distance that the light travels through the solution, and c is the concentration of the absorbing species per unit volume.

A silly (correct) example of multiplication with sig figs is: 164 × 1 = 200. Mixed operations: If you have a problem with mixed addition/subtraction and multiplication/division, keep all of the digits until you’re finished, but keep track of the last sig fig in each step by putting a line over it.

All nonzero numbers are significant, so in 123.45, there are five sig figs. Also, all zeros in front of a number without a decimal point in front of them are insignificant, so in 00460, there would still be just two sig figs. You may use decimal notation or scientific notation as in these examples 0.0350 ; 3.50e-2. Trailing zeros in large integers are always counted by this script. 2008-04-23 · 2 or 3 sig figs?
