What is made by adding 4.5 moles of NH3 to 250ml of water.what is the molarity?

Well molarity means moles per litre. So here, you need to multiply by 4 as 250x4 is a litre. 4.5*4 is 18 molar.

What is the number of moles of solute in 250 mL of a 0.4M solutionon centration?
1 mole in 250 ml and 4 moles in 1 liter or 1000 mls
What is the molarity of 5 L solution that contains 3.59 moles of solute?
The molarity is 0.718 moles/litre.
If 25 moles of sucrose are mixed into 50 liters of water what is the molarity?
Molarity = moles of solute/Liters of solution Molarity = 25 moles sucrose/50 liters H2O = 0.5 M sucrose
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 )
How is molarity expressed?
Molarity is expressed in moles per litre of solution.
What is the molarity of 80g magnesium chloride dissolved in 250ml of water?
MgCl2 Molarity = moles of solute/Liters of solution ( 250 ml = 0.250 L ) Get moles MgCl2 80 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.8402 moles MgCl2 Molarity = 0.8402 moles MgCl2/0.250 Liters = 3.4 M MgCl2 ----------------
What is the number of moles of solute in 250 mL of a 0.4M solutionon centration?
1 mole in 250 ml and 4 moles in 1 liter or 1000 mls
How do you calculate moles from molarity?
Number of Moles = concentration * volume (in litres)
Moles of a solute per kilogram of a solvent?
The number of moles of solute dissolved in 1 L of a solution would be the molarity. As an example, if you had 2 moles of solute in 1 liter the molarity would be 2M.
What is the molarity of 5 L solution that contains 3.59 moles of solute?
The molarity is 0.718 moles/litre.
750 ml of 20M HCl is mixed with 250 ml of 60M HCl What is the new molarity?
Molarity of a solution is the number of moles of the solute divided by the volume of the solution (in liters). If 750 ml of 20M HCl is mixed with 250 ml of 60M HCl, we first find the total number of moles of HCl in our new solution. Using that same formula, M=moles/V, we cansee that moles=MV. In the first solution we have (20M)(0.750L) = 15 moles. In the second, (60M)(0.250L) = 15 moles, so we have a total of 30 moles in our new solution, which also has a volume of 750mL + 250mL = 1L. The molarity of the new solution is 30 moles/1L = 30M
If 25 moles of sucrose are mixed into 50 liters of water what is the molarity?
Molarity = moles of solute/Liters of solution Molarity = 25 moles sucrose/50 liters H2O = 0.5 M sucrose
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 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 )
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 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 is molarity expressed?
Molarity is expressed in moles per litre of solution.
