Answer:
0.719 moles of NH₃
Explanation:
Molar mass of ammonia 17 g/mol
Mass of amonia = 12.23 g
Mass / Molar mass = Moles
12.23 g / 17 g/mol = 0.719 moles
The solubility of a sample will decrease when the size of the sample increases.
When the Size of sample is bigger, it means there is more particles that make up that sample so the amount of solvent to dissolve the sample will also be in the greater amount. Thus, when the sample size increases the solubility decrease. We can also say that size of sample and solubility are inversely proportional to each other.
The Hall-He'oult process is expensive and consumes large amounts of
energy to produce Aluminum.
Answer:
The weight percent of NaCl in the container is 21.5%
Explanation:
Given that,
Mass of NaCl = 168.90 gram
Mass of water = 616.00 grams
We need to calculate the weight percent of NaCl in the container
Using formula of percentage of weight
Put the value into the formula
Hence, The weight percent of NaCl in the container is 21.5%
