Answer:
0.27 moles
Explanation:
Find the mass of BaCl2 using the atomic masses on the periodic table
137.33+35.45*2=208.23 grams
Convert to moles
56 grams BaCl2 * 1 mol/208.23 grams= 0.268933391
N=1.2·10²⁴
Nₐ=6.0221·10²³ mol⁻¹
n₂(H₂O)=4 mol
n₁(H₂O)=N/Nₐ
n=n₁+n₂=N/Nₐ+n₂
n=1.2·10²⁴/6.0221·10²³ + 4 = 5.99 mol
5.99 <span>moles of water are in the glass</span>
Is this a chemistry pun? It's <span>carbon.</span>
My part of the atom, I'm guessing you are referring to the protons, neutrons, and electrons.
The smallest of these three is the electron.
