If 25.5mg of oxalic acid dihydrate are dissolved in 1.00 ml of solution what is the molarity of the resulting solution?
To calculate the molarity, you need to know the molar mass of oxalic acid dihydrate (C2H2O4•2H2O) which is approximately 126.07 g/mol. First, convert 25.5 mg to grams (0.0255 g), then calculate the number of moles using the molar mass. Next, divide the number of moles by the volume of solution in liters (1.00 ml = 0.001 L) to find the molarity which is 0.255 M.
molar mass H2C2O4 = 2*1 + 2*12 + 4*16 = 90.0 g/mol = 90.0 mg/mmol
25.5 mg in 1.0 ml = 25.5/90.0 mmol/ml = 0.283 mmol/ml = 0.283 mol/L = molarity oxalic acid

A sample of 76g of NaCl is dissolved to make 1L of solution. what is the molarity of the solution?
1.3g
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 the molarity of a solution consisting of 0.250 mol NaCl dissolved in 2.25 L of solution?
The molarity of the solution is calculated by dividing the moles of solute (0.250 mol NaCl) by the liters of solution (2.25 L). Molarity = moles of solute / liters of solution Molarity = 0.250 mol / 2.25 L = 0.111 M
What is the molarity of a solution with 0.207 mol of calcium acetate dissolved in a total volume of 166.5mL?
Molarity = moles solute/liters solution = 0.207 moles/0.1665 L = 1.24 molar (3 sig. figs.)
What is the term for the concentration expression that relates the moles of solute dissolved in each liter of solution?
Molarity, abbrev. M, units: mol/L, mmol/ml
Is the lower the molarity the higher the concentration or the lower the molarity the lower the concentration?
The lower the molarity, the lower the concentration. Molarity is a measure of the concentration of a solute in a solution. A lower molarity means there is less solute dissolved in the solution, resulting in a lower concentration of the solute.
What is the molarity of 4mol of NaOH dissolved in 2L of water?
The molarity of a solution is calculated by dividing the number of moles of solute by the volume of the solution in liters. In this case, the molarity of the solution with 4 mol of NaOH dissolved in 2 L of water would be 2 M.
A sample of 76g of NaCl is dissolved to make 1L of solution. what is the molarity of the solution?
1.3g
25.5 grams of lead fluoride in .088L of solution would have molarity?
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
Definition of molarity and its equation?
molarity is the number of moles dissolved per volume of a solution in dm cube molarity=mass of solute in gram __________________ 1 * _________________ molecular mass of solute volume of solution in dm cube OR molarity=no.of moles ________________ volume of solution in dm cube
What is the molarity of sodium borate?
The molarity of sodium borate (Na2B4O7) would depend on the concentration of the solution. To calculate molarity, you would need to know the amount of sodium borate dissolved in a known volume of solvent. Molarity is expressed in moles of solute per liter of solution.
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 the molarity of a solution consisting of 0.250 mol NaCl dissolved in 2.25 L of solution?
The molarity of the solution is calculated by dividing the moles of solute (0.250 mol NaCl) by the liters of solution (2.25 L). Molarity = moles of solute / liters of solution Molarity = 0.250 mol / 2.25 L = 0.111 M
What is the molarity of a solution in which 0.597 moles of HCl are dissolved in 0.169 liters of solution?
The molarity of the solution is calculated by dividing the number of moles of solute by the volume of solution in liters. In this case, the molarity would be 0.597 moles / 0.169 L = 3.53 M.
What is the ratio between the moles of dissolved substance and volume of solution in cubic decimeters?
Molarity
What is the amount of dissolved substance in a solution called?
The amount of dissolved substance in a solution is called the concentration of the solution. This can be expressed in various units such as molarity, molality, or weight/volume percentage.
What is the molarity of 6 moles of NaCl dissolved in 2 L of water?
6mol/2L
