Question

The quantity 0.0000064 g expressed in Scientific notation is

Answer 1

Answer : The answer in scientific notation is, $6.4\times 10^{-6}g$

Explanation :

Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example :

5000 is written as $5.0\times 10^3$

889.9 is written as $8.899\times 10^{-2}$

In this examples, 5000 and 889.9 are written in the standard notation and $5.0\times 10^3$  and $8.899\times 10^{-2}$  are written in the scientific notation.

As we are given that the measurement of mass in standard notation. Now we have to convert it into scientific notation.

Given standard notation : 0.0000064 g

The scientific notation will be, $6.4\times 10^{-6}g$

Answer 2

6.4 times 10^-7 is the answer because you are moving your decimal places to the left so it will be negative 7
