Answer:

Option b - $0.000000000012=1.2\times 10^{-11}$ grams.

Step-by-step explanation:

Given : Harry reads that a particular element has an atom with a mass of 0.000000000012 grams.

To find : What is the weight of the atom expressed in scientific notation?

Solution :

Scientific notation is a way of writing a number either very large or very small.

To write a number into scientific notation when a number between 1 and 10 is multiplied by a power of 10.

We have given the number 0.000000000012.

After decimal there are 12 digits.

Taking decimal before 1 having 11 digits

Therefore, The number is re-written as

$0.000000000012=1.2\times 10^{-11}$

So, Option b is correct.
