What is the molarity of a solution with 2.3 moles of sodium chloride in 0.45 liters of water?
RMM OF NaOH= 23+16+1= 40g/mol # mol of NaOH= 42/40= 1.05 mol Concentration= mol/dm 1.05 mol=2.3dm3 X mol = 1 dm3 X=(1.05*1)/2.3 X=.04565M
How many moles of sodium hydroxide are required to neutralize 0.20 mol of nitric acid?
Balanced Equation. NaOH + HNO3 >> NaNO3 + H2O Now, Molarity = moles of solute/liters of solution 0.800M HNO3 + mol/2.50L mol of HNO3 = 2 2mol HNO3 (1mol NaOH/1molHNO3 )(39.998g NaOH/1mol NaOH ) = 79.996 grams
What is the molarity of a solution where 4.00 moles of Potassium Chloride is dissolved in 3.00 L of solution?
The molarity of a solution given by the number of moles divided by the volume it contains. Hence, the molarity of KCl is 4.00/3.00 = 1.33 mol/L.
What is the molarity of the solution where 0.5 g of NaCl is dissolved to make 0.05 L of solution?
Given: 0.5 g NaCl; 0.05 L of solution.1) Find the molar mass of NaCl.(22.99) + (35.45) = 58.44 g/mol of NaCl2) Convert grams of NaCl to moles of NaCl.(0.5 g NaCl) X (1 mol NaCl / 58.44 g NaCl) = 0.00855578 mol NaCl3) Use the molarity equation, M = mol / L, to solve for molarity (M).(0.00855578 mol NaCl / 0.05 L) = 0.17 M
What would you be need to do to calculate the molarity of 10 mol of NaCl in 200?
Convert the 200 mol of water to kilograms of NaCl
What is the molarity of a solution of 95 grams of NaOH to 450 ml of water?
95g NaOH * 1 mol NaOH/ = 2.375 mol NaOH 40g NaOH Molarity (M) = mol / L M = (2.375) / (0.450) M = 5.28
What is the molarity of 6 moles (mol) of NaCl dissolved in 2 L of water?
This molarity is 3 mol/L.
What is the molarity of 1 mol of Na3Po4 dissolved in 2L water?
0.5M apex
How much heat is released when 3.600 mol naoh is dissolved in water?
-1602 kJ
If 24g of table salt dissolved in 2liters of water what is the concentration of salt in the form of a ratio?
Concentration = Molarity = mol/L24 g NaCl = ?? mol NaCl?? mol NaCl/2 L water = ?? M (M is unit of molarity)
What is the molarity of a solution with 2.3 moles of sodium chloride in 0.45 liters of water?
RMM OF NaOH= 23+16+1= 40g/mol # mol of NaOH= 42/40= 1.05 mol Concentration= mol/dm 1.05 mol=2.3dm3 X mol = 1 dm3 X=(1.05*1)/2.3 X=.04565M
What is the molarity of 2.3 grams of Sodium Chloride dissolved in 25 ml of water?
1,574 mol/L NaCl
0.0255 mol potassium hydroxide was dissolved in water to yield 10.0 mL of solution what is the molarity of the solution?
Molarity = Moles/Unit VolumeSo here Molarity = (0.0255) / (10-2) = 2.55 M
What is the molarity of a solution made with 128 grams of magnesium chloride dissolved in one liter of water?
Molarity= moles/Liters To change grams to moles you divide by the mole weight which is listed on the periodic table. Mol= grams/mol weight The Mole weight of Magnesium Chloride is 59.8 grams/mol Mol=128g/59.8 Mol=2.14 Now, you put the number of moles and Liters into the equation Molarity=2.14 mol/1L Molarity=2.14 So, the molarity is 2.14 M
What is the molarity of a solution that has 6 mol of CaCl2 in 3 kg of water?
The molarity is 2 mol/L.
How many moles of sodium hydroxide are required to neutralize 0.20 mol of nitric acid?
Balanced Equation. NaOH + HNO3 >> NaNO3 + H2O Now, Molarity = moles of solute/liters of solution 0.800M HNO3 + mol/2.50L mol of HNO3 = 2 2mol HNO3 (1mol NaOH/1molHNO3 )(39.998g NaOH/1mol NaOH ) = 79.996 grams
4.00 grams of NaOH have been added to water and made up to 2.00 liters of solution so what is the molarity of this solution?
[4.00 (g) / 40.0 (g/mol)] / 2.00 (L) = [0.100 (mol)] / 2.00 (L) = 0.0500 mol/L
