Molarity (M) = mols/liters. In this case:M = 2.0 moles / (.200) Liters = 10 Molar.


Molarity means moles per litre. Whatever you do to the litres to convert them to 1 litre, you have to also do to the moles. 0.732/975*1000 is 0.75077 molar.


Molarity = moles of solute/liters of solution Molarity = 0.597 moles HCl/0.169 liters = 3.53 M HCl ------------------


Molarity = moles solute/liters solution = 0.207 moles/0.1665 L = 1.24 molar (3 sig. figs.)


Molarity = moles of solute/Liters of solution Molarity = 10 moles salt/20 Liters solution = 0.50 M salt solution ----------------------------


6 moles. Work: 2-Molar solution = X (solute) / 3 liters (solution) 2(3) = 6 X=6



moles of a solute in a solution = mass of the dissolved solute/molar mass of the solute


6 moles of solute dissolved in 4 liters of solution.


Molarity = moles of solute / liters of solution moles = Molarity x liters = 0.150 x .250 = 0.0375 moles


Molarity (M) = mols/liters. In this case: M = 0.2 moles / (.200) Liters = 1 Molar.


0.125 Molar solution! Molarity = moles of solute/Liters of solution Algebraically manipulated, Moles of copper sulfate = 2.50 Liters * 0.125 M = 0.313 moles copper sulfate needed ===========================


Molarity means moles per litre. So we have to divide 8 by 3 here. This gives us 2.667 molar NaOH.



Molarity = moles of solute/Liters of solution ( 1500 mL = 1.5 Liters ) Molarity = 0.800 moles NaOH/1.5 Liters = 0.533 M sodium hydroxide ==================


Molarity = moles of solute/liters of solution ( 50 ml = 0.05 liters ) 2.50 Molar NaCl = moles NaCl/0.05 liters solution = 0.125 moles NaCl ( 7.305 grams NaCl )



Molar means moles per litre. Therefore, you need to divide 1.4 by 3.2 to get an answer per litre. 1.4/3.2 is 0.4375 molar.


Molarity = moles of solute/Liters of solution Molarity = 0.250 moles NaCl/2.25 Liters = 0.111 M NaCl --------------------


Yes if you have 3 liters of 12 Molar HCl if you dilute it with water and then pour 3 liters of the diluted HCl it wont be 12 Molar anymore


Molarity = moles of solute/liters of solution ( 300 ml = 0.300 liter ) 0.250 molar KOH = moles KOH/0.300 liters = 0.075 moles KOH



Molarity or molar concentration is a unit of concentration, symbolized by "M". It is the ratio of the number of moles of solute and the volume of solution (in liters).Molarity = Moles of solute ÷ Liters of solution = moles/liter = Mmolarity is define as the number of mole of a solute in 1 liter of solution.



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.
