Question

The characteristic of 6.02 x 10^23 is:
a) 6.02
b) 10
c) 23
d) none of these​

Answer 1

10²³ = 100000000000000000000000 (23 zeroes)

∴ 6.02^23=6.02×100000000000000000000000

  =602000000000000000000000

Hence 6.02 x 10²³ is the same as 602,000,000,000,000,000,000,000

***  Number of units in one mole of any substance (defined as its molecular weight in grams),  is called Avogadro's number.it is equal to 6.02214076 × 10²³.

                                       OR

6.02 × 10²³

Ans :-d) none of these​

Answer 2

Answer:

Option d none of these

Step-by-step explanation:

Concept

• A number system is a way of expressing numbers through writing. It is the mathematical notation for consistently representing numbers in a set using digits or other symbols. It represents the arithmetic and algebraic structure of the figures and provides a unique representation for each number.

Given

6.02×$10^{23}$

Find

Characteristics

Solution

The number of significant figures in scientific notation is determined by the number of digits between 1 and 10.

Thus, the number 6.02×10

23

 contains 3 significant figures.

All the three digits (6,0 and 2) are significant.

Option d
