Answer:yes because due to ionization atom makes chemical bonds with other atoms, which makes change in the properties of atoms
Explanation:
Answer:
6.6023g
Explanation:
To create a 0.247 M solution required weight of barium hydroxide.
0.247 x 171.346 =42.322g per liter
Therefore required mass for 156g of water = 42.322 x 0.156 = 6.6023g
(125 mg Na) x (1 g/1000mg) x (1 mol of Na/22.99 g) = 5.43 E -3 mols of Na
5.43 E -3 mols x 6.022 E 23 = 3.27 E 21 Na atoms
