A coefficient and a power of 10 What is coefficient? The first part that is usually between 1 and 9.99 and the second part, which is power of 10 that can be anything. examples...* 454000 = 4.54 x 105 moving the decimal 5 places to the left* 0165 = 1.65 x 10-2 moving the decimal 2 places to the right. Using the example 1.5 x 102, what number is coefficient and what number is the power of ten? 1.5 = coefficient102 = power of 10 What is the scientific notation of the diameter of the Eearth 12 8000 000 m? 1.28 x 107 m What is the scientific notation of the mass of a typical human 68 kg? 6.8 x 101 kg What is the scientific notation for the length of a pox virus 0.000 03? 3 x 10-5 cm In a number 10 or larger, the decimal point is moved where? to the left to give a positive power of 10 In a number less than 1, the decimal point is moved where? to the right to give a negative power of 10 Select the correct scientific notation for 0.000 0008 m 1) 8 x 106 m 2) 8 x 10-6 m 3) 0.8 x 10-5 m The correct answer is 2) 8 x 106 m Select the correct scientific notation for 72 000 g 1) 7.2 x 104 g 2) 72 x 103 g 3) 7.2 x 10-4 g The correct answer is 1) 8.2 x 104 g Write this as a standard number 2.0 x 10-2 L The correct answer is 0.020 L Write this as a standard number 1.8 x 105 g 180 000 g AuthorMon ID66646 Card SetScientific Notation DescriptionChemistry Scientific notation Updated2011-02-16T06:44:08Z Show Answers
