Myrcene is a hydrocarbon found in the essential oils of certain plants. It has a molecular formula of C10H16. If a sample of pure myrcene was analyzed and found to
contain 90.0 grams of carbon, how many grams of hydrogen would it contain?

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)
