How many moles are contained in 1.44 x 10^23 molecules of water?

The plant food contains nh4)3po4 what tests would you run to verify the presence of the nh4 ion and the po4 ion

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.

What are the two basic types of satellites
