Use the eq'n
moles = [conc] X vol(mL) / 1000
Algebraically rearragne
[conc] = moles X 1000 / vol(mL)
[conc] = 0.002 X 1000 / 2000 mL
[conc] = 0.002 X 1/2
[conc] = 0.001 mol L^-1 or 0.001 M

∙ 10y agoMolarity is moles per litre. So you have to make the 0.002 moles per 2 litres ratio to account for per litre. i.e. 2/2 is 1, so 0.002/2 is 0.001. The answer in 0.001 molar.

What is the molarity of 80g NaOH dissolved in 1L of water?
80g of NaOH dissolved in 250ml. of water find the molarity of this solution ?
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 ----------------------------
0.0255 mol potassium hydroxide was dissolved in water to yield 10.0 mL of solution what is the molarity of the solution?
Molarity = Moles/Unit VolumeSo here Molarity = (0.0255) / (10-2) = 2.55 M
What is the molarity of a solution with 5 moles of lithium flouride dissolved in 200 mL of water?
Molarity is per litre. Therefore 200x5 is a litre. so 5x5 is 25. The answer is 25 molar.

0.0255 mol potassium hydroxide was dissolved in water to yield 10.0 mL of solution what is the molarity of the solution?
Molarity = Moles/Unit VolumeSo here Molarity = (0.0255) / (10-2) = 2.55 M
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.
Molarity of 734 grams of lithium sulfate are dissolved to make 2500ml of solution?
Because you have 6.68 moles of Li2SO4 and 2.500 liters of water, the overall molarity of your solution is 2.67 M.
What is Molar Solutions?
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 that contains 55 grams of copper chloride dissolved in 1500 mL of water?
0.27 M
How do you find the concenration of a solution?
Concentration of a solution is recorded in molarity (M). Molarity is the moles of solute divided my liters of solution. So to find the concentration of a solution, calculate the number of moles of the solute (the chemical being dissolved) and measure the number of liters of the solution (the water), then divide them.
What is the molarity of a solution with 5 moles of lithium flouride dissolved in 200 mL of water?
Molarity is per litre. Therefore 200x5 is a litre. so 5x5 is 25. The answer is 25 molar.
