$1.4\times10^{-8}$ Centimeters

Work Step by Step

To answer this problem, we must multiply the number of angstroms by the number of centimeters each angstrom represents. The resulting answer would be as such: 0.000000014 To put this number into scientific notation, you must move the decimal place 8 places to the right, to represent this we must use this 8 as the exponent for the 10 when multiplying it by the constant, however since this number is less than 1, we must make this exponent negative to represent it properly, as shown in the answer.
