Question

A single electron has a charge of 3.7×10−15 Z . Using zeets and a fictitious unit of mass called the wiggle, w, the charge-to-mass ratio of an electron is 3.9×106 Z/w . What is the mass of an electron in wiggles?

Answer 1

assuming Z stands for charge
$$\large 3.7\times 10^{-15}Z \cdot \frac {1 w }{3.9 \times 10^6 Z }= ~?$$

Answer 2

w=9.487*10^-22
