How many moles of potassium hydroxide are required to make 200cm3 of 0.5M solution?
0.1 moles
What is the molarity of 6 moles of NaCl dissolves in 2 L of water?
Molarity is defined as moles solute/liter of solution6 moles/2 liters solution = 3 molar NOTE: This assumes no volume change and 2L is the final volume of solution.
What volume of solvent should be added to 36.8 g of CH3OH to produce a 0.500 M solution of CH3OH?
36.8 g x 1 mol/32 g = 1.15 moles0.500 M = 0.500 moles/L1.15 moles/x L = 0.500 moles/Lx = 2.3 liters
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.
How many moles of aluminum are required to produce 4 moles of hydrogen?
This is not a common reaction at standard temperature and pressure.
How do you calculated the value for molarity?
Molarity= No. of moles of solute/Volume of solution(in litre) or No. of moles of solute*1000/Volume of solution(in ml)
To calculate the molarity of a solution, you need to know the moles of solute and the?
You need to know the moles of solute and the VOLUME of SOLUTION.
Could you calculate the molarity of a solution you need to know the moles of solute and the?
volume of the solution
How many moles of potassium hydroxide are required to make 200cm3 of 0.5M solution?
0.1 moles
How many moles of sodium chloride are needed to prepare 500 mL of a 0.250 M solution?
500ml = 500cm3 = 0.5dm3 0.250M = 0.250mol/dm3 number of moles = molarity x volume number of moles = 0.250mol/dm3 x 0.5dm3 = 0.125mol 0.125mol of NaCl is needed to prepare the required solution.
What is the molarity of 6 moles of NaCl dissolves in 2 L of water?
Molarity is defined as moles solute/liter of solution6 moles/2 liters solution = 3 molar NOTE: This assumes no volume change and 2L is the final volume of solution.
Definition of molarity and its equation?
molarity is the number of moles dissolved per volume of a solution in dm cube molarity=mass of solute in gram __________________ 1 * _________________ molecular mass of solute volume of solution in dm cube OR molarity=no.of moles ________________ volume of solution in dm cube
What volume of solvent should be added to 36.8 g of CH3OH to produce a 0.500 M solution of CH3OH?
36.8 g x 1 mol/32 g = 1.15 moles0.500 M = 0.500 moles/L1.15 moles/x L = 0.500 moles/Lx = 2.3 liters
What is the volume of 3.0 M solution of NaCl made with 526g of solute?
Need to find moles NaCl. 526 grams NaCl (1 mole NaCl/58.44 grams) = 9.0 moles NaCl --------------------------------now, Molarity = moles of solute/Liters of solution or, for our purposes Liters of solution = moles of solute/Molarity Liters of solution = 9.0 moles NaCl/3.0 M = 3.0 liters in volume ---------------------------------
How many mole of KI required to produce 0.4 moles K2HgI4?
the required equation is HgCl2+4KI>>2KCl+K2HgI4. according to stoichiometric calculations 4 moles of KI gives 1 mole of k2HgI4 THEREFORE 0.4 moles of K2HgI4 requires----- ? 0.4 moles x 4 moles/1 mole=1.6 moles therefore 1.6 moles of KI is required to produce 0.4 moles of K2HgI4
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.
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
