HELP!! I'M COMFUSED!

The mass of particle A is approximately 6.5 x 10^-8 grams and the mass of particle B is 8.8 x 10^-27 grams. Approximately how many of particle B have the same mass as one of particle A?​

Answer 1

Take the ratio of the 2 numbers:

`\frac{6.5 * {10}^( - 8) }{8.8 * {10}^( - 27) } = 7.4 * {10}^(18)`

This means that it takes 7.4×10^18 particle Bs to equal the mass of particle A.
