Molarity means moles per litre. Therefore you have to multiply by 5 in converting 200ml to a litre. 2*5 is 10 moles per litre.

Molarity = moles of solute/volume of solution M = 0.25 moles/0.50L = 0.5M

Molarity = moles of solute/liters of solution Molarity = 7 moles solute/2 Liters solution = 3.5 M ======

The molarity is 0.718 moles/litre.

molar mass H2C2O4x2H2O = 2+24+64+36 = 126 g/molemoles = 2.38 g x 1mol/126 g = 0.0189 molesmolarity = 0.0189 moles/0.200 L = 0.0944 M

molarity = moles/litre [solution] = 6 mol/2 L [solution] = 3 M

Molarity = moles of solute/Liters of solution Molarity = 0.202 moles KCl/7.98 Liters = 0.253 M KCl solution ================

3.78 (g H2C2O4.2H2O) / 126.068 (g.mol-1 H2C2O4.2H2O) = 0.02998 (mol H2C2O4.2H2O) Molarity = moles of solute per Liters of solution = 0.02998 (mol H2C2O4.2H2O) / 0.200 (Liters) = 0.150 (mol.L-1 H2C2O4.2H2O) Answer: Molarity = 0.150 M

Molarity is moles of solvent divided by liters of solution, so 6.42 / 1.75 = 3.67M.

This molarity is 13 M; but this solution doesn't exist.

31 grams HCl (1mol/36.458g ) = 0.850 moles 500cm^3 = 0.50 Liters Molarity = moles of solute/liters of solution Molarity = 0.850mol/0.50L = 1.7 Molarity

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.

It is not important whether this '200 ml of solution' is countable without or without the hydrated compounds contribution of H2C2O4.2H2OAt first find moles of this3.78 grams H2C2O4 . 2H2O ( 1 mole cpd./126.068 grams)= 0.02998 moles H2C2O4 . 2H2OSince Molarity = moles of solute/Liters of solution ( 200 ml = 0.200 Liters )Molarity = 0.02998 moles H2C2O4 . 2H2O/0.200 Liters= 0.150 M H2C2O4.2H2O

The answer is 0,625 moles.

The definition of molarity is moles in every litre. Therefore if you have 4 moles in 8 litres, you have 4/8 moles in a litre. So you have 0.5 molar.

Molarity is moles divided by volume in Litres.So 8.5/2.3 = 3.7 mole/L = 3.7 M

Molarity means moles per litre. You have to keep that same ratio. i.e. .55moles in 0.5 litres is the same as 1.1 moles in a litre. Therefore the molarity is 1.1 molar.

Molarity = moles of solute/Liters of solution Molarity = 5 moles solute/4.5 Liters of solution = 1 M 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.

Molarity = moles of solute/liters of solution Molarity = 5 moles sucrose/0.5 Liters = 10 M sucrose solution =================

Molarity = moles of solute/Liters of solution Molarity = 6 moles AgClO4/2 Liters = 3 M AgClO4 =========

Molarity means moles per litre. So here you have to divide the moles by 75 and multiply by 1000. 0.5/75*1000, which is 6.667 molar.

Molarity is moles per litre. You need to convert the concentration so that it is in moles per litre. 0.4/500, x 1000 is 0.8 molar.
