Answer to Question #232303 in General Chemistry for Yos

Question

A single electron has a charge of 6.0×10⁻¹⁵ Z. Using zeets and a fictitious unit of mass called the wiggle, w, the charge-to-mass ratio of an electron is 9.6×10⁶ Z/w. What is the mass of an electron in wiggles?

Answer 1

The conversion factor to use in this case is:

charge / mass = 9.6 x 10^6 z / w

We are given that:

charge = 6.0 x 10^−15 z

Therefore the mass is calculated by combining the two equations:

4.5 x 10^−15 z / mass = 5.4 x 10^6 z / w

mass = 5.76 x 10^-22 w
