How does would you make 1 liter out of 2 moles?
By using a 2Molar solution.
Convert moles per liter into micro moles per liter?
1 mole = 106 micromoles
What is the molarity when water is added to 2 moles of sodium chloride to make 0.5 liter of solution?
Molarity is calculated as moles of solute divided by volume of solution in liters. In this case, you have 2 moles of sodium chloride in a 0.5 liter solution. So the molarity would be 2 moles / 0.5 L = 4 M.
How many moles of solute do you need to make one liter of a 1.25 molL ammonium hydroxide solution?
You need 1,25 moles ammonia.
How much grams of NaCl crystals are required to prepare 0.1N NaCl solution?
Molar mass of NaCl =~58.4 g/mole0.1 N NaCl = 0.1 moles/liter To make 1 liter of 0.1N NaCl thus requires 0.1 moles/liter = 0.1 moles x 58.4 g/mole = 5.84 moles Dissolve 5.84 g (6 g using 1 sig. fig.) in a final volume of 1 liter to make 0.1N NaCl
Why is it possible to calculate equlibrium constant using amounts rather than concentrations?
By amount I assume you mean moles. The amount of moles per liter and the amount of moles are the same if you calculate from 1 L (which is what you do when you have, for example, 0,30 M) 0,30 M = 0,30 mol/liter, if you have 1 liter that means you have 0,30 moles. So you can use either moles or mol/liter.
How many moles of Lithium chloride need to be added to one liter of total solution to make up a 1.25 M solution?
1.25 moles of Lithium Chloride
Calculate the volume of solution needed to dissolve 0.25 moles NaCl to make a 3.0M solution?
3.00 M, or 3 moles per (L) "liter" calls for having 3 moles per liter of the solution. The question asks how many moles must be in 250ml of a solution that has 3 moles per Liter. You must ask yourself what percent of 1 Liter is 250mls? Since there are a thousand ml in one liter, (1000ml=1L), then 250ml is exactly 25% of a Liter, or .25L. So, 250ml can only hold 25% of the 3.00 Molarity. Meaning that you multiply 3 x .25 and get .75 moles.
What type of animals make nest in the ground?
There are a few types of animals that make nests in the ground. These animals include snakes, rats, mice, rabbits, and moles.
How many moles of nitrogen does it take to fill a 60.0 liter space of stp?
The answer is 2,68 moles.
What is the concentration of in 0.15 of M of K2S?
If you have 2 moles of K+ for every mole of K2S and Molarity (M) is Moles per Liter. Then you know that you have .30 M of K2S. The way that you do that is setting up a series of conversion factors like so:(.15moles k2s/liter) x (2 moles of K/ 1 mole of K2S) = .30 moles k/ liter.The moles of K2S cancel out and you are left with moles of K per liter.
What is the molarity of the resulting solution obtained by mixing 2.5liter of 0.5M urea solution and 500 ml of 2M urea solution?
The 0.5M and 2M refer to moles per liter (of solution). Volume of final solution is 2.5 L + 500 mL = 2.5 L + 0.5 L = 3.0 L. So find out how many moles the final solution has and divide by 3.0L.First solution (0.5 moles/liter)*(2.5 liter) = 1.25 moles2nd solution (2 moles/liter)*(0.5 liter) = 1 moleMolarity: (1.25 mole + 1 mole)/(3.0 liter) = 0.75 moles/liter = 0.75 M
