Which formula can be used to calculate the molar mass of water (h2o)?

2 × molar mass of h + 2 × molar mass of o

molar mass of h + 2 × molar mass of o

2 × molar mass of h + molar mass of o

molar mass of h + molar mass of o

What is the equilibrium constant of aa+bb=cc+dd

Define dew point. i am writing this part to be able to ask the question

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)
