how many grams of calcium nitrate are needed to make a 500ml volume of a .5 molar solution
FeS + 2HCl >> FeCl2 + H2S 75 grams FeS (1mole FeS/87.92 grams)(2 mole HCl/1 mole FeS) = 1.71 moles HCl 2 Molar HCl = 1.71 moles HCl/Liters = 0.855 Liters HCl, or as asked for; 855 milliliters of hydrochloric acid needed
I suppose that this solution doesn't exist.
Only a compound has a molar mass not a solution.
Hydrochloric acid has a molar mass of 36.5 grams per mole. To prepare 100 mL of a 3M solution add 10.95 grams of HCl to 100 mL water.
The mass is 0,8 g.
100mL is needed to neutralize 50 ml of a 0.2 molar solution of HCL.
It depends on the concentration, but a 1 molar solution will have a pH of 0
The solution is 4 Molar.
