What is the %(m/m) of a solution containing 25.7 g of lithium fluoride (LiF) dissolved in 79.3 g of water?
Lithium metal reacts with
molecular fluorine gas to form lithium fluoride. A closed container
of volume 1.00 x 103 mL contains fluorine gas at 99.2 °C
and 4.66 x 103 Torr. Then 1.27 g of solid lithium is
introduced, and the reaction goes to completion. What is the final
pressure (in Torr) if the temperature rises to 198.7 °C?

The addition of 117 g potassium fluoride to 601 mL of water (d = 1.00 g/ml) causes the temperature to rise 3.50 °C. What is the AHgoln for KF? kJ/mol Exactly 19.5 mL of water at 34.0°C is added to a hot iron skillet. All of the water is converted to steam at 100.0°C. The mass of the skillet is 1.30 kg. What is the change in temperature of the skillet? "С
The addition of 115.0 g potassium fluoride to 605.0 mL of water (d = 1.00 g/ml) causes the temperature to rise 3.91 °C. What is the A Hoxn for KF? (Assume cp = 4.18 J/g °C.) * 11.78 kJ/mol
8. What is the percent by mass of lithium nitrate in a mixture of lithium nitrate and lithium carbonate if 0.500 g of the mixture reacts with (excess) 6 M aqueous solution of nitric acid to give 0.673 g of lithium nitrate? Water and carbon dioxide are the other products of the reaction. Assume that all lithium nitrate that could be made was and was isolated and weighed.
