First of all, you have to know what substance you are dealing with. Then you would have to know its density. Using the density you can convert liters to kilograms. Then you get the gram-molecular weight (using the chemical formula of this substance and the Periodic Table of Elements) and with that you can convert kilograms to moles.
You cannot. However, you can change moles to moles per litre (molar, M), if you know what vilume you are making the solution to. If the volume you are making the solution up to is in millilitres, divide the moles by the amount of millilitres, and then multiply by 1000. This will give you a concentration in terms of molarity.
Mole is a unit of mass, litre is a unit of volume.
You can not do that. They are totally different facts.
22.4L=1 mole of gas at STP
For gases, at STP, 1 mole = 22.4L.
1 mole = 22.4 Liters of gas
Molarity = moles of solute/Liters of solution Or, for our purposes, Moles of solute = Liters of solution * Molarity Moles Na2CO3 = 10.0 Liters * 2.0 M = 20 moles Na2CO3 --------------------------
Molarity = moles of solute/Liters of solution (40 ml = 0.04 Liters) algebraically manipulated, Moles of solute = Liters of solution * Molarity Moles HCl = (0.04 Liters)(0.035 M) = 0.0014 moles HCl ==============
You convert the mL to liters and use the equation: M=moles/L Using that you should be able to get the molarity....
Molarity = moles of solute/Liters of solution Molarity = 5 moles sucrose/0.5 Liters = 10 M ----------
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.
Moles/Liters=Molarity (M) therefore: Molarity*Liters=moles Since you were given milliliters, you must first convert your volume to liters for the equation to be accurate. 2.2M*.065L=moles=.143 moles NaOH
Molarity = moles of solute/Liters of solution Without the solute name the mass ( 8 grams ) does no good. Mass of solute (1 mole/molar mass of solute) = moles solute ----------------------then use Molarity equation. ( remember convert to liters )
Molarity = moles of solute/Liters of solution Or, for our purposes, Moles of solute = Liters of solution * Molarity Moles Na2CO3 = 10.0 Liters * 2.0 M = 20 moles Na2CO3 --------------------------
Molarity = moles of solute/Liters of solution ( 300 ml = 0.300 Liters ) For our purposes, Moles of solute = Liters of solution * Molarity Moles NaCl = 0.300 Liters * 0.15 M = 0.05 moles NaCl =============
Molarity = moles of solute/Liters of solution 3.42 M NaOH = 1.3 moles NaOH/Liters NaOH Liters NaOH = 1.3 moles NaOH/3.42 M NaOH = 0.38 Liters
Molarity = moles of solute/Liters of solution (40 ml = 0.04 Liters) algebraically manipulated, Moles of solute = Liters of solution * Molarity Moles HCl = (0.04 Liters)(0.035 M) = 0.0014 moles HCl ==============
Moles of solute ---------------- Liters of solution So, convert your grams to moles by dividing by the molar mass (add together the atomic masses of the solution) and then that will give you your moles. Divide that number by your 6.3 Liters. That number is your molarity.
Molarity = moles of solute/Liters of solution Molarity = 5 moles sucrose/0.5 Liters = 10 M ----------
You convert the mL to liters and use the equation: M=moles/L Using that you should be able to get the molarity....
first you need to know the number of liters and moles and the equation. you do someting then multiply the liters times the moles. first you need to know the number of liters and moles and the equation. you do someting then multiply the liters times the moles.
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 ( 22.0 ml = 0.022 Liters ) moles of solute = Molarity * Liters of solution Moles of NaCl = 0.500 M * 0.022 Liters = 0.011 moles of sodium chloride -------------------------------------------
