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 molarity a 500.0 ml solution containing 0.75 moles of solute?
Molarity = moles of solute/Liters of solution Without the solute name the mass ( 8 grams ) does no good. Mass of solute (1 mole/molar mass of solute) = moles solute ----------------------then use Molarity equation. ( remember convert to liters )
When a solution is diluted does it change the number of moles dissolved?
The number of moles of a solute will not change as a solution is diluted, however, the concentration of the solute will decrease. If you were to evaporate the water from the diluted solution, you would have the same number of moles of solute as when you started. You can test this by comparing the mass of the solute before producing the solution to the mass of the solute after the solution was diluted. The two masses should be the same.
What is the molarity of a solution consisting of 0.250 mol NaCl dissolved in 2.25 L of solution?
Molarity = moles of solute/Liters of solution Molarity = 0.250 moles NaCl/2.25 Liters = 0.111 M NaCl --------------------
How do you determine the molarity of a solution containing 18.2g C6H12O6and enough water to reach 6.3L?
Moles of solute ---------------- Liters of solution So, convert your grams to moles by dividing by the molar mass (add together the atomic masses of the solution) and then that will give you your moles. Divide that number by your 6.3 Liters. That number is your molarity.
What is the molarity of a solution in which 0.732 moles of HCl are dissolved in 0.975 liters of solution?
Molarity means moles per litre. Whatever you do to the litres to convert them to 1 litre, you have to also do to the moles. 0.732/975*1000 is 0.75077 molar.
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 molarity of a solution in which 0.597 moles of HCl are dissolved in 0.169 liters of solution?
Molarity = moles of solute/liters of solution Molarity = 0.597 moles HCl/0.169 liters = 3.53 M HCl ------------------
What is the molarity of 10 moles of salt dissolved in 20 liters of water?
Molarity = moles of solute/Liters of solution Molarity = 10 moles salt/20 Liters solution = 0.50 M salt solution ----------------------------
How many moles of copper sulfate are needed to make 2.50 Liters of 0.125 moles solution?
0.125 Molar solution! Molarity = moles of solute/Liters of solution Algebraically manipulated, Moles of copper sulfate = 2.50 Liters * 0.125 M = 0.313 moles copper sulfate needed ===========================
What is the ratio of moles of absolute to liters of solution called?
You think probable to molar concentration.
What is the molarity a 500.0 ml solution containing 0.75 moles of solute?
Molarity = moles of solute/Liters of solution Without the solute name the mass ( 8 grams ) does no good. Mass of solute (1 mole/molar mass of solute) = moles solute ----------------------then use Molarity equation. ( remember convert to liters )

What is the molarity of a solution that contains 1.4 moles in 3.2 liters of solution?
Molar means moles per litre. Therefore, you need to divide 1.4 by 3.2 to get an answer per litre. 1.4/3.2 is 0.4375 molar.
What is the molarity of a solution is defined as?
The concentration in moles of a substance in the solution
What is the molarity of a solution consisting of 0.250 mol NaCl dissolved in 2.25 L of solution?
Molarity = moles of solute/Liters of solution Molarity = 0.250 moles NaCl/2.25 Liters = 0.111 M NaCl --------------------
How many carbon atoms are there in 700 liters of a 2 molar Carbonic acid solution?
1400 moles.
