Molar mass H₂O = 18.0 g/mol
number of moles :
1.0 / 18.0 => 0.055 moles
1 mole -------------- 6.02 x 10²³ molecules
0.055 moles -------- ? molecules
molecules = 0.055 x ( 6.02 x 10²³) / 1
molecules = 3.311x10²² / 1
= 3.311 x 10²² molecules
hope this helps!
Answer:
D.
Explanation:
I just got it right in the test :)
Answer: Coastlines.
Explanation: South America's and Africa's shoreline interlocks perfectly. Which implies they must have been joined together in history.
Since the molar ratio of N2 to Nh3 is 2:1, you can make twice as much NH3 by using N2. Therefore, you can make a maximum of 4.5 mol of NH3 assuming 100% yield.
