The molarity of that solution is 0.82, based on sodium phosphate's molar mass and the given volume of solution. Since there are three sodium ions for every one formula unit of sodium phosphate, the molar concentration of Na+ ions is 0.82(3)=2.46.
332/1,000 = 332,000 parts per million
.02g/1000 * 1000000= 20ppm
The percent concentration is 13,75 %.
The answer is 0,0207 mol.
0.286
Solution of different concentrations can be prepared by the adequate choice of the solute amount and the volume of the solvent.
13,75 % NaCl
The concentration of ethanol is 11,7 %.
The percent concentration is 13,75 %.
The answer is 0,0207 mol.
500mg/l
The concentration of this solution (in NaOH) is 40 g/L.
Solvent
You prepare a solution by dissolving a known mass of solute (often a solid) into a specific amount of a solvent. One of the most common ways to express the concentration of the solution is M or molarity, which is moles of solute per liter of solution.
Look up or calculate the molecular weight/molar mass of FeCl3. Then... 40.0 g FeCl3/MW FeCl3/0.275 L = M (concentration of FeCl3 in solution)
1 % DCPIP solution can be prepared by dissolving 1g of the dye in 100cm3 of water

Iron (III) chloride has the molecular formula of FeCl3. Its molecular weight is 162.2 grams per mole. Concentration is moles of solute divided by volume of solution. Therefore, the answer is .224 moles per liter.
Solution of different concentrations can be prepared by the adequate choice of the solute amount and the volume of the solvent.
