Exercise 1 | Chemistry and the Scientific Method

Express the following number in scientific notation:

0.00302

105000

570 x 10-3 

0.0064 x 109 

628 x 10-5 x 102 


Express the following number in standard form:

1.22 x 10-3

6.3 x 105

5.0 x 10-6

0.00302 = 3.02 x 10-3

105000 = 1.05 x 105

570 x 10-3 = 5.70 x 10-1

0.0064 x 109 = 6.4 x 106

628 x 10-5 x 102 = 6.28 x 10-1


1.22 x 10-3 = 0.00122

6.3 x 105 = 630000

5.0 x 10-6 = 0.0000050
