#2. Percent error (or deviation) is calculated as ((TV-EV)/EV))*100
A mole is equal to 6.02x10^23, so one mole of H2O has 6.02x10^23 water molecules. To get how many of them are in 6 moles you need to multiple it by six:
(6.02x10^23)x6= 3.612x10^24
So, there’s 3.612x10^24 water molecules in 6 moles of water
Air does move from high to low pressure so true
Air is heterogenous mixture because it is made of components that can seperate, The process to sperate air into its components is called fractional distillation. In this process, air coverts to a liquid form, and then it seprates into seperate layers, which then helps you to see air's components.
hopefully this helps you.
