Answer

6.022 $\times$ $10^{23}$

Work Step by Step

We need to write 602,200,000,000,000,000,000,000 as the product of a number greater than or equal to 1 and less than 10, and an integral power of 10. The number greater than or equal to 1 and less than 10 will be 6.022 The decimal point has moved 23 places to the right, so the exponent of 10 will be 23. So, 602,200,000,000,000,000,000,000 = 6.022 $\times$ $10^{23}$
