A sample of 76g of NaCl is dissolved to make 1L of solution. what is the molarity of the solution?
1.3g
Of you have 5 moles of salt make 5 liters of solution what will be the molarity of the solution?
So molarity is moles in every litre. To get 5 litres down to 1 you have to divide. what you do to litres you have to do to moles. i.e. 5/5 is 1 molar.
Why doesn't adding one mole of solute to one liter of water make a one molarity solution?
molarity of moles of solute/liters of solution(not solvent) the volume of the solvent(even if it started at 1 L) would change after adding the solute depending on the molar mass, density, etc of the solute, the molarity would be different
Calculate the molarity of a solution of glycerol made by dissolving 43.000 mL glycerol at 15 degrees C in enough water to make 200.00 mL of solution?
2.89
A solution is made by dissolving 19.52 g of SnF2 into enough water to make 770 mL of solution What is the molarity of the solution?
the molarity is found by: 19.52g/770mL x 1 mole/156.7g x 1000mL/1L=0.618 mole i got 156.7g by using the chemical makeup of the solution SnF2: Sn's atomic number being 118.7 and rounding F's atomic number to 19.
A sample of 76g of NaCl is dissolved to make 1L of solution. what is the molarity of the solution?
1.3g
What is the molarity of a solution made by dissolving 23.4g of sodium sulphate in enough water to make up a 125ml solution?
The molarity of a solution made by dissolving 23,4 g of sodium sulphate in enough water to make up a 125 mL solution is 1,318.
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.
Molarity of 734 grams of lithium sulfate are dissolved to make 2500ml of solution?
Because you have 6.68 moles of Li2SO4 and 2.500 liters of water, the overall molarity of your solution is 2.67 M.
When 80g of sodium hydroxide are dissolved in water to make 0.500 of a solution what is the molarity?
4m
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
What is the molarity of a solution made by dissolving 3.09 moles of Nacl in 1.50 L of solution?
what is the molarity of a solution prepared by dissolving 36.0g of NaOH in enough water to make 1.50 liter of solution?
How to calculated NaOH concentration be affected if the colour change in the solution is too dark?
I presume you are titrating a standardized solution of (eg) HCl with NaOH to determine the molarity of the alkali. You would normally use an indicator which will change colour at the end point (eg colourless to pink for phenolphthalein). If the solution is very coloured to begin with it can mask the colour change and so make the end point hard to see and lead to a miscalculation of molarity.
If 3.0 mol of CaCl2 are added to water to make 0.500L of solution what is the concentration in molarity?
molarity is #moles divide by # liters, so 3.0 divided by 0.500 is 6.0 molarity (2 siginficant figures is all you are allowed)
Of you have 5 moles of salt make 5 liters of solution what will be the molarity of the solution?
So molarity is moles in every litre. To get 5 litres down to 1 you have to divide. what you do to litres you have to do to moles. i.e. 5/5 is 1 molar.
What is the molarity of a solution formed by mixing 20.0 g sulfuric acid with enough water to make 500.0 mL of solution?
0.408 M
What is the molarity of 20.2 g of potassium nitrate in enough water to make 250.0 mL of solution?
0.8M
