Question

How many grams of each of the following substances will dissolve in 100 ml of cold water? consult a handbook or the internet. (do not include the units in your answer)

Answer 1

Solubility data for specific substances like LaF3, CaCO3, Ag2SO4, and Pb(OH)2 can be found in reference material such as the Handbook of Chemistry and Physics. The example given, BaSiF6, has a solubility of 0.026 g/100 mL. Henry's law is used to adjust solubility calculations for gaseous solutes at different pressures.

Step-by-step explanation:

To determine how many grams of certain substances will dissolve in 100 mL of cold water, we must consult solubility data. For the compounds in question, the stratetgy would be to look up their respective solubility values in a reference like the Handbook of Chemistry and Physics. However, since specific solubility data for LaF3, CaCO3, Ag2SO4, and Pb(OH)2 are not provided here, we can use the related substances provided as an example.

For instance, the solubility of BaSiF6 is given as 0.026 g/100 mL. For such slightly soluble compounds, we can assume that the volume of water does not change significantly upon dissolution, allowing the direct conversion of this value to grams per 100 mL of water. If solubility data for 'LaF3', 'CaCO3', 'Ag2SO4', and 'Pb(OH)2' were available, you would use the same methodology to find the respective mass that will dissolve in 100 mL of water.
