a) 0.25 molar is the smallest amount and thefore the lowest concentration of NaCl.
The molar mass of NaCl (sodium chloride) is 58.44 g/mol. To find the molar mass of 3.00 mol of NaCl, you would multiply 3.00 mol by the molar mass of NaCl. For the 1.50 kg, you would first convert the mass from kilograms to grams (1 kg = 1000 g), then divide the mass by the molar mass to find the number of moles.
1 molar NaCl is 58.5 g of salt ( a mass) per liter (a volume).
This concentration is min. 150 mmoles/L NaCl.
Water and salt form a solution, not a mixture. All solutions of NaCl in water are "salt water," but if you get the concentration of NaCl over 3.5 percent they prefer to use the term brine.
Percent concentration could mean many things...MOLARITY is defined as the moles of solute per unit volume of solution so 5 moles of NaCl in one liter of solution would be 5M (molar) NaCl solution.(Note: Solution is the solvent and solute combined, usually the solid is added and then the solution is filled to a certain line once the solid has dissolved.)MOLALITY is defined as the moles of solute per kilogram of solvent (NOT solution). So 5 moles of NaCl in one kilogram of water makes 5 mol/kg NaCl. (sometimes the symbol m is used for molality but is often confused with the unit of meters).For other types of "percent concentration" of solutions check:http://en.wikipedia.org/wiki/ConcentrationA cursory glance seemed to confirm the accuracy of the information.
Example: 0,5 molar concentration of sodium chlorideThe molar mass of NaCl is 58,44 g; so 0,5 molar is 29,22 g/L
what is the molar mass for NaC1 !!!???!!!???!!!??? --- The molar mass of sodium chloride (NaCl) is 57,958 622 382.
i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2 i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2 i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2 i = isotonic molar [glucose] / isotonic molar [NaCl] i = 14 M / 7 M = 2
You start by checking how many moles of NaCl you have in your pool. Number of moles=concentration*volume =0.048mole/L*455000L=21840moles Then you get the molar mass of NaCl which is 58.443 g/moles, then you multiply it by your number of moles. 21840 moles*58.443g=1'276'395g=1'276.395kg of NaCl
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 )
The molar mass of NaCl (sodium chloride) is 58.44 g/mol. To find the molar mass of 3.00 mol of NaCl, you would multiply 3.00 mol by the molar mass of NaCl.

If 10 is 10 molar for you, this is a saturated solution of NaCl.
1 molar NaCl is 58.5 g of salt ( a mass) per liter (a volume).
This concentration is min. 150 mmoles/L NaCl.
5 moles of NaCl have 292,2 g.
The molar mass of sodium chloride (NaCl) is 58,44 g.
NaCl is the formula unit of sodium chloride; 0,9 NaCl is a solution, probable o,9 molar.
