Unveiling the Microscopic Universe: Exploring Atoms with Exponents and Scientific Notation Cont.

Having explored atomic sizes, Emma is interested in the concept of atomic count in a given mass. She decides to examine a cube of gold. Emma has a cube of gold that is [latex]1 \times 10^{-4}[/latex] inches on each side. She wants to figure out how many gold atoms are lined up along the edge of the cube. Can you help her?

Following her calculations with the gold cube, Emma discovers a tiny grain of sand and decided to estimate the number of silicon atoms in it. The small grain of sand Emma found weighs around [latex]1 \times 10^{-3}[/latex] grams. She knows it’s made mostly of silicon atoms, each weighing about [latex]4.6637 \times 10^{-23}[/latex] grams. Can you help Emma figure out approximately how many silicon atoms are in the grain of sand?

Congratulations on completing your journey with Emma! You’ve ventured into the atom-sized universe, applying your understanding of exponents and scientific notation to estimate the size and count of atoms. Emma appreciates your assistance and hopes that you continue practicing and exploring, unlocking more incredible secrets of our universe in the future!
