Given : A physicist discovers an element whose atom has a mass of 0.00000000000000112 grams.
He makes an entry in his journal
To Find : writes the mass in scientific notation
Solution:
Very large and very small numbers can be expressed in standard form.•
Standard form is also called scientific notation form
A number is written in scientific notation if it has the form c × 10ⁿ where
c > 1, c < 10, and n is an integer.
0.00000000000000112
= 1.12 x 10⁻¹⁵
= 1.12 E -15
E -15 is equivalent to 10⁻¹⁵
He makes an entry in his journal and writes the mass in scientific notation as
1.12 E -15
