35 g-----------------257 mL
x g------------------1 000 mL
x = (1000 x 35)/257 = 136,18 g
149,09 g------------------1 mol
136,18 g------------------x mol
x = 136,18/149,09 = 0,91 mol
149,09 is the molar mass of ammonium phosphate.

The molarity is o,2.
Molarity = moles of solute/Liters of solution Molarity = 0.250 moles NaCl/2.25 Liters = 0.111 M NaCl --------------------
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.
One mole of NaOH is 40g. So 40g dissolved in 1 litre will give a 1M solution.
It depends on the molarity of the solution
80g of NaOH dissolved in 250ml. of water find the molarity of this solution ?
The molarity is 0,031.
1.3g
The spectator ions are chloride and ammonium; the copper and phosphate ions precipitate from the solution as copper (II) phosphate.
The molarity is o,2.
Molarity = moles of solute/liters of solution Molarity = 0.597 moles HCl/0.169 liters = 3.53 M HCl ------------------
Molarity = moles of solute/Liters of solution Molarity = 10 moles salt/20 Liters solution = 0.50 M salt solution ----------------------------
Molarity = moles of solute/Liters of solution Molarity = 0.250 moles NaCl/2.25 Liters = 0.111 M NaCl --------------------

The concentration of a solution can be expressed in many ways. One of them is as the molarity of the solution. A solution with molarity equal to one has one mole of the solute dissolved in every liter of the solutions
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.
