A solution that does not contain enough solute?
A solution that only contains a small amount of solute, is a dilute or very dilute solution.
What is the molarity of a solution made by dissolving 23.4g of sodium sulphate in enough water to make up a 125ml solution?
To find the molarity, first calculate the number of moles of sodium sulphate using its molar mass. Sodium sulphate's molar mass is 142.04 g/mol. Next, divide the number of moles by the volume in liters (125 ml = 0.125 L) to get the molarity. This will give you the molarity of the sodium sulphate solution.
What is the molarity of a solution made by dissolving 3.09 moles of Nacl in 1.50 L of solution?
The molarity is calculated by dividing the moles of solute by the liters of solution. In this case, the molarity would be 3.09 moles / 1.50 L = 2.06 M.
HOW TO 0.1N NaOH solution preparation?
To prepare a 0.1N NaOH solution, dissolve 4g of sodium hydroxide (NaOH) pellets in enough water to make 1 liter of solution. Use a volumetric flask to accurately measure the final volume. Remember to handle NaOH with caution as it is a caustic substance.
How do you determine the molarity of a solution containing 18.2g C6H12O6and enough water to reach 6.3L?
To determine the molarity, first calculate the number of moles of C6H12O6 using its molar mass. Then, divide the number of moles by the total volume in liters to get the molarity. In this case, the molarity would be around 0.48 M.
What is the molarity of a solution formed by mixing 20.0 g sulfuric acid with enough water to make 500.0 mL of solution?
To find the molarity, start by converting grams of sulfuric acid to moles. the molar mass of sulfuric acid (H2SO4) is 98.08 g/mol. Divide the moles by the volume in liters (500.0 mL = 0.5 L) to get the molarity. Molarity = moles/volume (L).
Calculate the molar it’s oh a solution that contains 15.7 of CaCO3 dissolved in enough water to make 275mL of solution?
0.570 M (note the capital M, this is molarity.)
What is the molarity of 20.2 g of potassium nitrate in enough water to make 250.0 mL of solution?
To find the molarity, first calculate the number of moles of potassium nitrate using its molar mass (101.1 g/mol). This comes out to 0.2 moles. Then, divide the moles by the volume of the solution in liters (0.250 L) to get the molarity, which is 0.8 M.
2.431 g of h2c2o4 x 2h2o was obtained and dissolved in enough dI water to form 250.0 ml of solution what is the concentration of the resulting of h2c2o4 solution?
To find the concentration of the H2C2O4 solution, you first need to determine the molarity of the solution. Calculate the number of moles of H2C2O4 x 2H2O using its molar mass, then divide that by the volume of the solution in liters to find the molarity. Finally, remember to account for the stoichiometry of the compound in the calculations.
How do you solve freezing point depression problems when given only the molarity?
Calculating the freezing point depression of a solvent requires three pieces of information: 1) the molal freezing point depression of that solvent; 2) the molality of the solution; 3) the number of distinct entities produced in solution per molecular formula unit of solute. Hopefully you meant molality instead of molarity (if the solvent is water and it's a dilute solution, assuming that molality = molarity isn't a bad approximation). I suspect you've been told what 1 and 3 are (or been given enough information to figure them out) but simply didn't mention it; otherwise you're pretty much boned.
What is the molarity of a solution prepared by dissolving 1.56 grams of gaseous HCl in enough water to make 26.8 mL of solution?
The molar mass of HCl is 36.46 g/mol. So, 1.56 grams of HCl is equivalent to 0.0428 moles. Since the volume of the solution is 26.8 mL (0.0268 L), the molarity is calculated as 0.0428 moles / 0.0268 L = 1.60 M.
What is the molarity of the solution formed by mixing 0.20 mol of sodium hydroxide with enough water to make 150 ml of solution?
To calculate the molarity of the solution, first convert the volume to liters (150 mL = 0.150 L). Then, divide the moles of solute (0.20 mol NaOH) by the volume of solution in liters to get the molarity. Molarity = 0.20 mol / 0.150 L = 1.33 M.
