Magazine Problem 1
The mass of the Earth is approximately 5,970,000,000,000,000,000,000,000 kilograms. The mass of Mars is approximately 639,000,000,000,000,000,000,000 kilograms. Can you determine which mass is larger?
Problem 2
The mass of the Earth is approximately \(5.97 \times 10^{24}\) kilograms. The mass of Mars is approximately \(6.39 \times 10^{23}\) kilograms. Can you determine which mass is larger?
Problem 4
The radius of a hydrogen atom is approximately \(5.3 \times 10^{-11}\) meters. The radius of a chlorine atom is approximately \(1.8 \times 10^{-10}\) meters. Can you determine which radius is larger?
Problem 7
Write each of the following numbers in scientific notation. 0.00087
Problem 17
The mass of a proton is \(1.67 \times 10^{-27} \mathrm{~kg}\). The mass of an electron is \(9.11 \times 10^{-31} \mathrm{~kg}\). Divide these numbers using a calculator to determine approximately how many times greater the mass of a proton is than the mass of an electron.
Problem 19
The mass of a proton is \(1.67 \times 10^{-27} \mathrm{~kg}\). The mass of an electron is \(9.11 \times 10^{-31} \mathrm{~kg}\). What is the approximate mass of one billion protons? (Note: one billion is \(10^{9} .\) )
