If 1,1 is grams the molarity is 0,317.
The molarity is 0,031.
The solution is 4 Molar.
Molarity = moles of solute/volume of solution ( so, not a great molarity expected ) 4.60 grams H2SO4 (1mol H2SO4/98.086g) = 0.0469 moles/450ml = 1.04 X 10^-4 Molarity.
Molarity = moles of solute/volume of solution so, 29.4 grams sounds about right.
This molarity is 0,5.
The molarity is 2,973.
Molarity = moles of solute/volume of solution so, 125 grams of NaCl (1mol NaCl/58.44 grams NaCl) = 2.1389 moles NaCl/400 Liters = 0.00535 M NaCl
