To get moles. divide mass by molar mass.Molar mass of
Na is 23
and for Cl is 35.5.
the total molar mass of NaCl is 23+35.5 = 58.5mol/gUse the mass and divide by this number30.22g divide by 58.5mol/g and you will get 0.5166 mole.
Since the molecule has 1 Na to 1 Cl, and that the number of moles for NaCL is 0.5166. All of them would be 0.5166molesNa = 0.5166 x 1 = 0.5166molesCl = 0.5166 x 1 = 0.5166moles
to get number of atoms. Multiply your mole by Avogadro number which is 6.022x10^23Na = 0.5166 x 6.022E23 = 3.111x10^23Cl =  0.5166 x 6.022E23 = 3.111x10^23

These goats are eating grass on a sunny day. What is happening to the carbon in the air around the living things on the mountain
polet [3.4K]

Answer:

both

Explanation:

Carbon in the air around the living thing is moving in and out of its lungs. The movement is occurring at the same time. This is one of the most important gaseous exchange important to life.

  • The goats takes in oxygen gas from the surrounding and releases carbon dioxide in the process.
  • But, air is actually drawn in by the goat which is a mixture of several gases.
  • Air contains carbon dioxide which is a rich source of carbon
  • With the carbon dioxide from respiratory processes, the goat ejects and breathes out this waste carbon matter.
  • Therefore, the gaseous exchange in a goat involves the movement of carbon in and out of the air.
