An important number used in chemistry is Avogadro's Number which is used to describe the number of molecules in a mole of a substance (we will discuss Moles in another unit of this course). Look up this number and express it in scientific notation and in standard notation. 1. \( 3.022 \times 10^{22} \) 2. \( 4.97 \times 10^{24} \) 3. \( 6.022 \times 10^{23} \) Standard Notation 4. \( 6.022 \times 10^{-21} \) Scientific Notation 5. \( 602,200,000,000,000,000,000,000 \) 6. \( 602,200,000,000,000,000,000,000,000 \) 7. \( 622,322,000,000,000,000,000,000 \) Using a computer or other resource, determine the mass of earth in \( \mathrm{kg} \). Express this number in scientific notation and in standard notation. 1. \( 5.97 \times 10^{24} k g \) 2. \( 4.97 \times 10^{24} k g \) 3. \( 3.97 \times 10^{24} k g \) Scientific Notation 4. \( 5,970,000,000,000,000,000,000,000 \) Standard Notation 5. \( 3,970,000,000,000,000,000,000,000 \) 6. \( 4,970,000,000,000,000,000,000,000 \) 7. \( 5,970,000,000,000,000,000,000 \) Solve the following math problem using scientific notation. \[ \left(5.5 \times 10^{\wedge} 2\right)+\left(7.28 \times 10^{\wedge} 3\right) \] Solve the following math problem using scientific notation. \[ \left(5.02 \times 10^{\wedge} 3\right)-\left(3.1 \times 10^{\wedge} 7\right) \] Solve the following math problem using scientific notation. \[ \left(4 \times 10^{\wedge}-1\right)^{*}\left(6.8 \times 10^{\wedge} 10\right) \] For more information watch this video. Remember to report your answer with correct number of significant figures. Solve the following math problem using scientific notation. \[ \left(7.0 \times 10^{\wedge}-6\right) /\left(2 \times 10^{\wedge}-2\right) \] For more information watch this video. Remember to report your answer with correct number of significant figures. For the number \( 0.000420 \), the number of significant figures is Question 9 (2.71 points) For the number \( 6.02 \times 10^{23} \), the number of significant figures is
