.256 molar= 256 mols of solute per 1000ml of solution. Since there are 1000ml in 1L, there are 256 mols of BaCl2 for every liter. Multiply this by 1.5 and you get a total of 384 mols of BaCl2 in 1.5L of a .256 molar solution

Use the equation
moles = conc'n x vol / 1000
NB The '1000' is used to convert 'mL' to litres.
Substituting
moles(BaCl2) = 0.256 moles/L X 1.5 L / 1000
mol(BaCl2) = 0.384 moles.

What is the molarity of chloride ion in 100 ml of a 500 M barium chloride solution?
I assume you mean 0.5 molar, but I'll go with what I'm given. If you have 500 molar of barium chloride, you will have 1000 molar of chloride ions as there are 2 chlorides for every 1 molecule of barium chloride. Having the 100ml there is irrelevant as you are talking about concentration and didn't ask for moles.
What is the molar mass of aluminum chloride?
The molar mass aluminum chloride is 133,34 g (for the anhydrous salt).
Now assume you measure out exactly 2.0 ml of aluminum chloride into a third test tube How many moles of aluminum chloride are in the tube?
That depends upon the concentration of the solution. If it is a 1 molar solution, then 2 ml contain .002 moles.
What is the molar mass of Cesium Chloride?
the molar mass is 168.36 g/mol
How many moles of barium are present in a sample having a mass of 22.3 grams?
# of moles = grams of substance / molar mass of substance molar mass of Barium =137.33 grams/mole #moles of Barium = 22.3 grams/ 137.33 grams/mole = 0.162382582 moles

How can you express the concentration of a substance mathematically?
In chemistry, the concentration of a substance in solution is determined by molarity, which is symbolized by "M". This indicates the number of moles of a substance dissolved in one liter of a solvent (usually water). For example: - 1 mole of sodium chloride = 58 grams - If 116 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 2-molar (2 M) solution of sodium chloride. - If 232 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 4-molar (4 M) solution of sodium chloride.
What is the molarity of 2 moles of compound dissolved in r L of water?
Need to know the mass of BaCl2 in order to calculate molarity.
Can you prepare 1 liter of a .5-molar glucose solution?
The formula is C6H12O6 which is 180g/mole. Divide that in half for 90g in one liter of water for a 0.5 molar solution
What is the molarity when water is added to 2 moles of sodium chloride to make 0.5 liter of solution?
Molarity is calculated as moles of solute divided by volume of solution in liters. In this case, you have 2 moles of sodium chloride in a 0.5 liter solution. So the molarity would be 2 moles / 0.5 L = 4 M.
What is the molar solution?
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
What is it called when the concentration of a solution defined in terms of moles of solute per liter of solution?
This is a molar concentration.
What is the molar heat of solution for ammonium nitrate and calcium chloride?
81.1 kj/mol
A one molar solution of NaOH in water contains?
One liter of a one molar solution of NaOH in water contains 40g of NaOH. The quantity must be known.
What is Molar Solutions?
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
How many grams of magnessium chloride are in 1liter solution 2.5M?
Magnesium chloride has a molecular weight of 95.2, so 1 litre of 1 molar MgCl2 would have 95.2g. A 2.5 molar solution would have 2.5X95.2g per litre = 238grams
Sodium chloride molar mass?
The molar mass of sodium chloride is 58,44.
