Answer:
A. 2.107x10^24
Explanation:
1 mole is defined as the particles containing in 12g of 12-C. That is 6.022x10²³ particles.
When you say 1 mole of atoms means 6.022x10²³ atoms, 1 mole of molecules means 6.022x10²³ molecules, etc.
Now, 3.5 moles of H₂O are:
3.5mol * (6.022x10²³ molecules / 1mol) = 2.107x10²⁴ molecules of H₂O.
Thus, right answer is:
<h3>A. 2.107x10^24</h3>
70.5g x 1 mol / 58.5g = 1.2mol of nacl
Gas. Molecules in gas are able to move and vibrate around each other more freely than the molecules in liquids and/or solids due to the great amount of space in between them. Hope this helps! :)
Correct answer is D.
