Need moles NaCl first.
17.52 grams NaCl (1 mole NaCl/58.44 grams)
= 0.29979 moles NaCl
=====================Now.
Molarity = moles of solute/Liters of solution ( 2000 ml = 2 Liters )
Molarity = 0.29979 mole NaCl/2 Liters
= 0.1499 M NaCl

Calculate the molarity of a solution that contains 4.60 g of H2SO4 in 450 mL of solution?
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.
What is the molarity of a solution prepared by dissolving 2.24 grams of NaOH in a volume of 500.0ml?
Molarity = moles of solute/volume of solution 2.24 grams NaOH (1mol/33.998g) = 0.0659 moles NaOH/0.5 liters = 0.132 Molarity of NaOH
Calculate the molarities 98 grams of NaOH in 2.2 liters of solution?
4.00 grams of NaOH have been added to 2.00 liters of water. The molarity of this solution is?
How do you calculate grams of a compound in a solution?
- measuring the mass of this compound and the volume (or mass) of the solution - by chemical analysis (and determination of the concentration of this compound) If you know the molarity, multiply moles by molecular weight and adjust per the volume you have. If you don't know the molarity, a simple means is to just evaporate the solvent and weigh the remaining compound
How do you fnd the molarity?
Molarity = Grams/(Molecular Weight X Volume)
Find the molarity?
Molarity = Grams/(Molecular Weight X Volume)
Formula of molarity?
Molarity = Grams/(Molecular Weight X Volume)
What is the molarity of a solution prepared by dissolving 1.56 grams of gaseous HCl in enough water to make 26.8 mL of solution?
Find moles of HCl first. 1.56 grams HCl (1mole HCl/36.458 grams) = 0.0428 moles HCl Molarity = moles of solute/volume of solution Molarity = 0.0428 moles/26.8 ml = 0.00160 milli-Molarity, or more to the point; = 1.60 X 10^-6 Molarity of HCl
7.35 L of a 4 M NaOH solution contains how many grams of NaOH?
Molarity = moles of solute/volume of solution so, 29.4 grams sounds about right.
What is the molarity of a CaCl2 solution containing 330 grams of CaCl2 in 1 liter of solution?
The molarity is 2,973.
How much do you determine the molarity of a solution of 10 grams of NaOH in 500 mL of solution?
This molarity is 0,5.
What is the molarity of a solution that contains 1.1 of lithium in 0.5 liters of solution?
If 1,1 is grams the molarity is 0,317.
