Question

The mass of the electron, 0.000,000,000,091 kg, can be written in shorthand notation as A. 9.1 x 10^(-11) kg B. 9.1 x 10^(-12) kg C. 9.1 x 10^(-10) kg D. 9.1 x 10^(-9) kg

Answer 1

Answer: 9.1 x 10^(-11)

Step-by-step explanation

The exponent -11 means "move the decimal point 11 spots to the left".

This will mean the 9.1 becomes 0.000,000,000,091

There are 10 copies of "0" between the decimal point and the "91".
