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

A 20.0 mL sample of CuSO4 was evaporated to dryness leaving 0.967g of residue What was the molarity of the original solution?
Molarity = moles of solute(CuSO4)/volume of solution(Liters) 0.967 grams CuSO4 (1 mole CuSO4/159.62 grams) = 0.00606 moles CuSO4 Molarity = 0.00606 moles/0.020 liters = 0.303 Molarity
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.
How does the amount of solute moles and grams relate to the density and molarity of the solution?
Increasing the amount of the solute in the solution the molarity and the density of this solution increases.
What is the molarity of0.73 g MgCl2 in 300 mL of solution?
Molarity = moles of solute/volume of solution. 0.73 grams MgCl2 (1mol/95.21g ) = 0.00767 moles/0.300 Liters ( to get M, not mM ) = 2.6 X 10^-2 M
What is the molarity of 2.0 L sodium hydroxide solution containing 10.0 grams solute?
The molarity is 0,125 M.
How do you calculate molarity of substance?
Molarity (M) = mole of solute (mol)/volume of solution that it is dissolved into (L) Make sure that the volume is converted to L if it isn't already, otherwise you will get wrong answers.
A solution of NaOH contains 20g of this compound in 2dm3 of this solution . What is molarity of this solution?
This sodium hydroxide solution has a molarity of 0,25.
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 many grams of solid NaOH are needed to prepare 500mL NaOH solution with a concentration of 0.4M?
molarity equals moles of solute /volume of solution in litres . moles of NaOH equals 5g/40g = 0.125 and volume of solution will be volume of water + volume of NaOH = 0.5 litre+0.002 l which is nearly 0.5 litre . (volume of NaOH is calculated by its density) so molarity = 0.125mol/0.5litre = 0.25 M
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
How do you calculate normality of percent solution?
Is the makeup of the solution expressed as "percent by mass"? If so, to calculate molarity (or normality), you have to also know the density of the solution Step 1. Lets say the solution is 14%, and the density is 1.09 g/mL. We can write the following: (14 grams solute/100 grams solution) (1.09 grams solution/ mL solution) Step 2. Multiplying and cancelling from step 1 gives you 15.26 grams solute / 100 mL solution. Multiplying top and bottom by 10 gives you 152.6 grams solute per liter. Step 3. Molarity is number of moles per liter. Divide the 152.6 grams of the solute by the forumua weight (or molecular weight) of the solute, and you have the number of moles of solute. This number is therefore the molarity of the solution. If the solution is "percent by volume", the number you have is number of grams per 100 mL. Multiply by 10, and you have grams per liter. Then divide by the formula weight, and you have the molarity.
A 20.0 mL sample of CuSO4 was evaporated to dryness leaving 0.967g of residue What was the molarity of the original solution?
Molarity = moles of solute(CuSO4)/volume of solution(Liters) 0.967 grams CuSO4 (1 mole CuSO4/159.62 grams) = 0.00606 moles CuSO4 Molarity = 0.00606 moles/0.020 liters = 0.303 Molarity
Find the molarity?
Molarity = Grams/(Molecular Weight X Volume)
How do you fnd the molarity?
Molarity = Grams/(Molecular Weight X Volume)
What is the molarity of a solution containing 8 grams in 500 mL of solution?
It depends highly on the compound to be dissolved and the solvent. Molarity is measured my moles per litre, and if you don't know the molar mass of the compound, you can't work out the molarity.
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.
What is the molarity of a CaCl2 solution containing 330 grams of CaCl2 in 1 liter of solution?
The molarity is 2,973.
