How big is an atom compared to a quarter?
A quarter is huge compared to an atom. To put them in perspective let's calculate how many atoms are in a US quarter: -The current US quarter has a mass of 5.67g and is 8.33% nickel and 91.67% copper. -From the mass and percentages of each element we can find that there are 5.20g of copper and 0.472g of nickel in each quarter. -Dividing the mass of each element by its molar mass we find that there are 0.0818 moles of copper and 0.00805 moles of nickel in each quarter. -Multiplying the number of moles of each element by Avogadro's number we find that there are 4.93x1022 atoms of copper and 4.85x1021 atoms of nickel in each quarter. This means there is a total of 5.41x1022 atoms in a US quarter. Let's write that number out to get a little more perspective: 54,100,000,000,000,000,000,000 That certainly is a huge number!
