In scientific notations, numbers are expressed in the form of N × 10n, where ‘n’ is an exponent with positive or negative values and N can have a value between 1 to 10.
e.g. i. The number,
602,200,000,000,000,000,000,000 is expressed as 6.022 × 1023.
ii. The mass of a H atom,
0.00000000000000000000000166 g is expressed as 1.66 × 10-24g.
iii. The number 123.546 is written as 1.23546 × 102.
iv. The number 0.00015 is written as 1.5 × 10-4
