Question

A certain solution has hydrogen ion concentration of 0.0000653 miles per liter write this number in scientific notation.

Answer 1

Solution:

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. In this case, we have that:

$0.0000653=653x10^{-5}$

so that, the correct answer is:

$653x10^{-5}$
