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 molecules are in one mole of sucrose?
1 M = 1 mole/liter. so 2 M sucrose would contain 2 moles of sucrose in 1 liter of solution.So to find the volume of solution with 1 mole sucrose:V = (1 mole) / ( 2 mole/liter) = 0.5 liter ; 0.5 liter * (1000 mL/liter) = 500 mL
How many grams of NaCl would you dissolve in water to make a 0.5 M NaCl solution?
0.5 M means 0.5 moles per liter. so it depends on how many liters of solution that you need.Suppose you want to make 1 liter of solution, then you need 0.5 moles of NaClFrom the webelements.com Periodic Table:Atomic mass of Sodium (Na) = 22.990 & Atomic Mass of Chlorine (Cl) = 35.453So 1 mole of NaCl = (22.990 + 35.453) grams = 58.443 gramsBased on the 1 liter, we want to add 0.5 moles: (58.443 grams/mole)*(0.5 mole) = 29.2215 g (to make 1 liter of 0.5 M solution)
How could one make a 2 M solution of a compound?
Dissolve 2 moles of the compound in enough water to make a final volume of 1 liter.
What If enough water is added to 5 g of HCl to make 1 liter of solution what is the pH?
Find moles HCl. 5 g HCl (1 mole HCl/36.450 grams) = 0.1372 moles HCl Now, Molarity = moles of solute/Liters of solution Molarity = 0.1372 moles HCl/1 liter = 0.1372 M HCl Then. -log(0.1372 M HCl) = 0.9 pH ( you might call it 1, but pH can be off the scale ) -----------

Convert moles per liter into micro moles per liter?
1 mole = 106 micromoles
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
How many molecules are in one mole of sucrose?
1 M = 1 mole/liter. so 2 M sucrose would contain 2 moles of sucrose in 1 liter of solution.So to find the volume of solution with 1 mole sucrose:V = (1 mole) / ( 2 mole/liter) = 0.5 liter ; 0.5 liter * (1000 mL/liter) = 500 mL
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 KBR are there in 100 mL if a 0.75 M Solution?
There would be 0.75 moles in 1 liter of solution. You have 100 mL which is in fact 0.1 liters. so you would have 0.1 of 0.75 moles. 0.1 x 0.75 = 0.075 moles.
How many grams of NaCl would you dissolve in water to make a 0.5 M NaCl solution?

What are the Steps how to make 3M KCl?
Since you know the molecular mass of KCl is 74.55, that can be set up as a fraction: 74.55 grams/ 1 mole. You want a 3 molar solution and (for simplicity sake) you want 1 Liter. This can be expressed as the fraction: 3 moles / 1 Liter If you set these equations next to each other (find the product--multiply them), you can cancel out the units that exist on both the top and bottom, which in this case are the moles: 74.55 g / 1 mole * 3 moles/1 Liter = 74.55 g/1 * 3/1 Liter Since the denominator is 1, this is really just 74.55 g * 3/Liter -or- 223.65 grams/Liter ("223.65 grams per Liter").
5.8 grams in 1 liter of water equals how many moles?
if you have 100 liters how many moles does that equal?
How many moles of 1 liter solution?
Depends on the concentration of the solution and what is in it.
How could one make a 2 M solution of a compound?
Dissolve 2 moles of the compound in enough water to make a final volume of 1 liter.
Conc of glucose in human blood is90 mgperdeciliter What is molarity of glucose in human blood is?
Molarity is moles divided by liters (M/L). 90mg is 0.09g. Since 1 mole of glucose weighs 180 grams, 0.09g/180g = 0.0005 moles. 1 deciliter is 1/10 of a liter, so there are 0.0005 moles in 1/10 of a liter, hence 0.005 moles in 1 liter, or 0.005 M/L. Sound about right?
