B. 4.45x10^24 molecules
C. 5.54x10^23 molecules
D. 6.02x10^23 molecules
^ is raised to the _ power
2. Explain what conversion factors you would need to use to convert 35 miles to centimeters.

What is the percentage composition of carbon in the compound ch4

Helium decays to form lithium. which equation correctly describes this decay?

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
