When hot lava reaches seawater, the salts in the water react with the steam to form gaseous hydrochloride acid. you are given a unbalanced chemical equation for one such reaction and the volume of hci(g) produced. explain how you would find the mass of solid sea salt needed to produce the given gas volume.

NaCl + H2O = HCl + NaOH 
FIRST write the equation and balance the equation THEN convert the volume of the gas to moles of the gas PV=nRT THEN according to the stoichiometry of the reaction one mol of gas is produced by one mol of salt. Convert the mol of gas to mol of salt FINALLY calculate the molar mass of the salt and convert the mol of salt to g of salt (m= nxMM)
