Did the Turks have control of the holy by the end of the crusades?

They attacked Christian pilgrims from Europe and closed pilgrimage routes to Jerusalem, hope this helped :)

There are a number of ways to express concentration of a solution. This includes molarity and molality. Molarity is expressed as the number of moles of solute per volume of the solution.  MOlality is expressed as moles per kg solution. 

5.25 mol H2SO4 / kg solution ( 1 kg / 1000 g ) ( 1.266 g / mL ) ( 1000 mL / 1L ) = 6.6 M H2SO4
