How is the molar mass if a molecule determined? what are it’s units?

In the space, show a correct numerical setup for calculating the number of moles of co2 present in 11 grams of co2

Anyone who's in connections academy chemistry b have the factors that affect the rate of a reaction portfolio already done?

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)
