What is the molarity of a 800. mL solution of magnesium bromide if 57.42 g of MgBr2 is dissolved in water?

Sagot :

molar mass magnesium bromide (MgBr2) = 184 g/mole
0.0939 mol/L x 0.720 L = 0.06761 moles MgBr2 required
0.06761 moles x 184 g/mole = 12.4 grams MgBr2 required (to 3 significant figures)
