If 1,1 is grams the molarity is 0,317.
The molarity is 0,41 mol/L.
Molarity = moles of solute/liters of solution 2500 milliliters = 2.5 liters ------------------------------------ 12.2 grams SrCl2 (1 mole SrCl2/158.52 grams) = 0.07696 moles strontium chloride -------------------------------------------------------------------------------------------------------- so, Molarity = 0.07696 moles SrCl2/2.5 liters = 3.07 X 10 -2 M SrCl2 -------------------------------------
20 grams /385, x 1000 is 51.948 grams per litre. The molecular weight of sucrose is 342.3g/mol. 51.948/342.3 is 0.15176 molar.
The molarity is 0,125 M.
If 1,1 is grams the molarity is 0,317.
The molarity is 0,031.
31 grams HCl (1mol/36.458g ) = 0.850 moles 500cm^3 = 0.50 Liters Molarity = moles of solute/liters of solution Molarity = 0.850mol/0.50L = 1.7 Molarity
