<span>It will take 409 liters of water to dissolve 1.00 grams of barium sulfate at 20°C
Barium sulfate is almost insoluble in water. At 20°C, only 2.448 x 10^-3 grams will dissolve in 1 liter of water. So take the amount of barium sulfate and divide by its solubility.
1.00 / 2.448 x 10^-3 = 408.49 liters.
Since we only have 3 significant figures, round the result to 3 figures.

Answer:
6) 225.8 g
7) 1.01 g
8) 21.624 g
Explanation:
6) Molar Mass of Lithium Bromine: 86.845
86.845 * 2.6 = 225.8 g
7) Molar Mass of Neon: 20.180
20.180 * 0.05 = 1.01 g
8) Molar Mass of Water Vapor: 18.02
18.02 * 1.2 = 21.624 g
Answer:
Cold coffee
Explanation:
The higher the temperature of something, the more kinetic energy it will have. The colder coffee's molecules will have less kinetic energy than the hot coffee's molecules
