Question
(II) A typical atom has a diameter of about 1.0 $\times$ 10$^{-10}$ m. ($a$) What is this in inches? ($b$) Approximately how many atoms are along a 1.0-cm line, assuming they just touch?
Step 1
We know that 1 meter is approximately equal to 39.37 inches. Therefore, we multiply the given diameter by this conversion factor: \[1.0 \times 10^{-10} \, \mathrm{m} \times \frac{39.37 \, \mathrm{in}}{1 \, \mathrm{m}}\] Show more…
