Concentrated hydrochloric acid is an aqueous solution that is 31.50 % HCl. The density of the solution is 1.19 g/mL. What mass of HCl is contained in 0.734 L of solution?

275.1399 g

Explanation:

density of HCl = 1.19 g/mL

Conc. of HCl in solution = 31.5%

volume of solution = 0.734L = 734mL

mass of solution = density x volume = 1.19*734 = 873.46 g

HCl mass in solution = 873.46 * 31.5% = 275.1399 g

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
