A rigid cylinder with a movable piston contains a sample of hydrogen gas. At 320. K, this sample has a pressure of 160. kPa and a volume of 3.85 L. What is the volume of this sample at STP? (Make sure you round your answer to the correct number of significant figures) *

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
